Welcome newcomer!
I know this has been done several times before and I’m sure they did it better than me, but here goes.
Revolver frame designations:
D Frame: Agent, Cobra, Diamondback, Police Positive and Special, Viper Detective Special, Commando Special, etc.
E/I Frame: Official Police, Officers Model, Python, Trooper. (Lumped together)
F Frame: Navy, Pocket Navy, Walkers, Dragoons etc.
G, K, Q Frame: 22 Scouts and 22 New Frontier Scouts, Buntline Scouts etc.
J Frame: Trooper MKIII, Lawman MKIII, Official Police MKIII. Metropolitan MKIII.
P Frame: Single Action Army.
SF Frame: SFVI, DSII, Magnum Carry.
AA Frame: King Cobra,
V Frame: Peacekeeper, Trooper MKV, Lawman MKV
MM Frame: Anaconda.
I don’t know if the 1917 and New Service had their own frame names, but perhaps Lonewolf will help out on this one.
I think a good reference book for frame designations would be the Numrich Gun Parts catalog.
(Note: Corrected entries in V Frame and J Frame on 8/4)
