What a thread! Zombies and all. Great info in here and a great read.
sue2teach2u; welcome to the forum.
Your K225xxx would have been in the 1954 neighborhood if it were a Model 14,15,16,17,18,19,48,53,66,67 and 68 (or the pre-model versions) but not if it is a Model 10. It would not have a K prefix if it is a Model 10.
Does it have a fixed sight (a grove cut into the rear of the top strap?
This is a Model 10 from 1962
This is a K-38 from 1957. Notice the difference in the rear sight between the two revolvers.
