What I am wanting to do is have a heavy barrel for each dash number. Which logically would start with a 10-1. However, I haven't seen a heavy barrel on a gun below 10-6. I wonder if production on some dash numbers between -1 and -6 were pencil only?
Thus, I am curious if there are any available production records that spell out exactly what configurations were produced for each dash number.
Thanks a lot for the responses.
