In order to have or need the designation of "pre" when discussing a particular handgun, its required, I would think, that the model or specific type (however it was referred to) gun was made both prior to and following the introduction of model numbers. So guns that ceased production prior to 1957 and those whose manufacture began after 1957 would never have a "pre-model" version, correct? I am curios what's the list of guns that there are "pre-model" versions of? Obvious there's pre 27, pre 29 but Im guessing there's a bunch. Some may have long since gone away but if they spanned the just the right few years in the mid and late 50's then their out there, right?
