SMITH & WESSON, MODEL 3000

[TJ-Flames]

Hi guys

I know an oldish guy, who has a S&W, model 3000(based on Remington 870) pump action
bought it new in '79
it has a long barrel, 4 round mag
he has maybe put 50rds through it, he is looking to sell it as apparently he is to old to re-lisence it or something, even though he had a long serving military career in SWA and Rhodesia.
The shotgun was also bought in SWA at the time, he also has a beautifull leather bag with floral designs on it.

Now, seeing as this topie is very dear to me, and I wouldn't want him being done in.
How much would such a gun be worth now?

Thanks in advance

Barrel Length ? Ribbed ? 12G? Choked or allows for Multichokes ?
