A example of how in days of yore guns were bought and modified for use as the owner saw fit- I have seen Texas Ranger SAA's with the Fitz mod.
No one put their guns in the safe with the box for their widows to sell after they croaked.
A Pard of mine who started to shoot the SAA in the 40's told me that the fire control system- the "safe" is the hammer with the old Colt. No one kept their finger out of the trigger guard. Cocking the fanged hammer was putting the old thumb buster "off safe"
The past is another country for sure- things were different then.
Really neat not sure if I would fix it up or not. Those grips are out standing as well.
If the owner got it in '44 before he deployed- wonder if he took it to war?
Looks like a broken "O" to my old eyes. What a cool gun! I think I'm more on the "fix it" side, but I totally understand the "leave it be" side as well. Depends on the Owner. (or current caretaker)
OP, this is what your .357 Magnum looked like when it was new, except with the 5 1/2" barrel…..
At first glance they don't look much alike. But even today yours and mine have many similar or identical characteristics such as the low profile front sight, barrel caliber marking that does NOT include the word "Magnum" such as is found on 2nd and 3rd generation SAA's, bright sides on the hammer (rather than case colored as found on earlier 1st generation SAA's), late first generation cylinder beveling, prominent 2 lines patent dates, and "broken O" in the word "Hartford" in the barrel address.
I would be VERY proud to own your .357 Magnum just as is; that gun just screams character!
The front of the trigger guard is old west gunslinger style, the guard interferes with quick access to the trigger, most revolvers were not carried in holsters, that was Hollywood. I think it adds character to an already unique revolver.
