For 750 I'd run as fast I could with it. I do not own one but would love to. My buddy told me to look out for that generation.

To me I see case color hardening on trigger and hammer and that tells me hammer mounted firing pin and forged parts.

On this gun I believe there is one MIM part and that is the thumb release. I have that on my 29-6 (with forged trigger, hammer) and the MIM release is smooth and excellent. Not a deterrent at all.

Throats should measure exact on that gun and this will shoot modern hardball really well which some of the old 25 will not.
