Ed, if you can determine the model (sometimes marked on the gun), you might be able to get an approximate range of dates. The first V-C I ever owned, I wrote to them for further information. They told me they no longer had the records. However, based on the model, they were able to tell me when it first appeared (1933), and even sent me pages from a period catalog describing the model in question. Didn't nail down the specific year of production, but very helpful. In fact, really more helpful than just having a date.
