The Calace with the big neck I tried a few weeks ago was recently made prob 2011 or 2010. It would be good to take a look at the one locally so you can see how the neck is.
The eBay listing for the Eastman is no longer there. The seller of the 1962 Calace is Schlegel who posts here a fair amount and who is an aficionado of Italian bowlbacks. I have a feeling that it is a nice one and if you have your heart set on a Calace and the local one does not meet your needs, that one might be a good bet.
