Need to change the list, the Smith Model 45 is either a Pre-Model 45 or both a pre-model and a model 45. I will have to check with Dave Nowack to see if his BPD Model 45 is a model 45 or a pre-model 45.
My new BPD is a pre-model 45, shipped in April 1957 with no model number on the gun. The 3rd edition says there were 20 guns BPD numbers 16T to 35T mine is 18T
