Re: Holdrio-Picolo pocket mandolin
I own a nearly identical one, which was given to my great-aunt by someone who used it in a college mandolin club in the 1920's or so. Mine has a tailpiece marked "Marcelli," which I gather was also common on German/European instruments. Mine is labeled "Holdrio-Picolo [note spelling] Mandolin, D.R.G.M., Made in Germany, W.V. Co. N.Y." It was apparently imported by whomever "W.V. Co." was. I gather "D.R.G.M." is "German Registered Design," a copyright, trademark, or patent indication.
An inexpensive, compact instrument, decent but not "fine" construction, with a three-piece back. Small voice, more a curiosity now than a useful instrument. Neat oddity, though.
