Re: Gibson History, serial numbers, FON's and such
Thanks Links..I will post that here for record keeping. This is fully consistent with the contentions I have been making lately
______________
Some of the pre-World War II Gibson banjo manufacturing dates that we commonly accept are incorrect.
Surviving pre-war Gibson factory records do not contain detailed and specific information about production dates for individual instruments. It is possible that Gibson never kept this data in the way that C.F. Martin and other manufacturers did. However, by combining other contemporary external source material and the surviving original Gibson factory records we are now in a position to make some badly needed adjustments to our Gibson banjo manufacturing chronology.
One of the first people to attempt the compilation of a pre-war Gibson manufacturing date system was Mr. Davis Kennedy. In a letter published by Bluegrass Unlimited magazine in March 1969, Mr. Kennedy laid out the first important information that would be used for years in assigning production dates for Gibson banjos. Davis Kennedy worked at Gibson as the Supervisor of the Custom Department from 1965 through 1968 and collected his data firsthand from the Gibson factory employees during that period. Roger Siminoff began building on that early data when Pickin’ Magazine published his Gibson Banjo “Serial Number” list in the 1970's. Vintage instrument dealers like George Gruhn, John Bernunzio, Stan Werbin, Stan Jay and legions of private individuals followed the example of these earliest pioneers and collected their own lists of Gibson numbers. These materials first became widely available in the 1990's when Tom Biggs placed a large collection of Gibson information on his Internet website.
As the data began to mount, cracks began to appear in the accepted dates. Tom Biggs originally voiced his concerns to me on this topic over 15 years ago. Other collectors began to see the problems as well, especially those who collected Gibson guitars and mandolins. The system used by the banjo enthusiasts simply did not square with information collected by the guitars and mandolin players. The situation worsened as original sales receipts surfaced, more catalogs were reprinted and a few nearly complete collections of Mastertone Magazine were complied. In his recent book even Jim Mills points out a few of the problems with our accepted chronology.
In retrospect part of the problem is clear. No single collector or dealer had enough data from which to draw valid conclusions. Gibson built over a hundred thousand instruments before World War II and a list containing 200 numbers or even 2,000 numbers is simply not enough data. Another problem is that bad information was repeated. In his original 1969 letter, Davis Kennedy stated that the first flat head Mastertones were built in 1932. But immediately afterwards he qualified that statement by writing that “no one knew for sure, but the most popular guess at Gibson was 1932.” Mr. Kennedy never intended that 1932 be taken as an absolute. But the information was repeated over and over again for years and unfortunately it was incorrect.
The confusing and inconsistent Gibson “system” of serial numbers and factory order numbers adds to the problem. Each batch of instruments built by Gibson during the pre-World War II period had a “factory order number.” This number was used by the accounting department to track the actual costs of manufacturing the instruments. The price of raw materials, finished sub-assembly parts and labor used in the production of each particular batch of instruments were tracked and assigned to that factory order number. High quality instruments like L-5 guitars and F-5 mandolins also received an actual serial number upon completion. Other mid-line instruments like banjos and lower quality guitars simply retained their factory order number with the addition of a bin number instead. Lower quality instruments often got no identifying numbers at all, even though they originally had a factory order number just like everything else.
In a 1970 interview former Gibson employee Wilbur Marker stated that the factory order numbers originated in the weekly production meetings. The senior staff gathered together each week and decided what would be produced in the near future. According to Wilbur Marker, a pre-printed and serially number form was used to initiate a production run. The number on this form became the factory order number. External evidence today shows that Gibson had been using the factory order number system as early as the 1910's and perhaps before that. Indeed, by the time the first Mastertone banjos rolled off the production line in April 1925 the factory order numbers were already in the 8,000 range.
It would also be naive to assume that the factory order numbers were always used in sequential order. Existing evidence shows this is simply not so. Some instruments took longer to sell, some took longer to produce. What began as a pile of pre-printed forms with sequential numbers was not always exactly in numerical order at the end of the production line. For the period from 1925 through 1930 they are nearly sequential, but from 1931 onwards chaos was the order of the day. In my examination of the 1935 shipping ledger sometimes I wonder if someone knocked over that pile of pre-printed forms and then just picked them up off the floor without returning them to sequential order.
The shipping ledgers also show another important fact. After the stock market crash of October 1929 Gibson had extreme difficulty selling plectrum (PB), regular (RB) and any gold plated banjos. One All-American tenor (9747-4) was shipped and returned nine times. By 1937 it is described as being “shop worn.” The final Mastertone banjo shipped prior to World War II was a style 6 which had been sitting around the factory since 1928. I have interviewed a Gibson employee who worked there in the period 1938-1940. He remembers seeing hundreds of dusty older instruments sitting around in the famous rolling racks. Some of them in a state of partial disassembly. The shipping ledgers themselves show that Gibson had a considerable back stock of instruments. These often appear in the ledger with the notation “TB-G old style” or simply “L-5 old.”
It is not difficult at all for me to believe that the Earl Scruggs RB-Granada was assembled in the first quarter of 1930, but not shipped until 1934. The shipping ledgers show that type of thing happened with regularity. Research on my book continues on a daily basis. Hopefully, I will be able to share a revised and more accurate Gibson banjo production chronology with everyone at a near date.
