New Service variations.....
For those of you who are Collectors, how do you, in normal conversation, distinguish between the variations of the old Colt New Service?
In the Smith line its "five screw", "pre-Model xx" etc.
The New Service was made with both the flat latch and rounded latch, straight barel and belled barrel. With or without the hammer block.
I'm not talkin New Service vs Shooting Master, but New Service series only.
