Need help on a Series 80 Gold Cup National Match

[heybert]

Hello everyone,
I need some help identifying any type of modification on this pistol. Don't know too much on it since my father got it on a trade. All he knows is that the person had the pistol tuned so that he can use it for competition. Anyway, before putting this on EE, thought I'd post some pic's and maybe someone can help identify any work done. We'll be canvassing some competition shooters also around here. Hopefully they can give us some insight also. I realize pic's won't necessarily give people clues on what's been done, but hopefully it would. Thank you.

Now the pic's:

Nice gun. Some mods:

Ambi safety
Magwell
Grips
Front sight
Rear sight
Beavertail
Slide stop should be bright stainless if gun was bright.
Looks like a full length guide rod is installed.
Mainspring housings are usually grooved not checkered.

What he said. Probably throated and polished ramp, trigger work etc.

Thanks guys. Much appreciated. What would be a good honest price for this pistol? My father told me that the person shot the pistol very little before he had to stop due to a health issue. The person never got a chance to compete with the pistol.
