Recently given 1920 Parker Trojan

[Novahunter]

Good morning everyone,

My uncle gave me a parker trojan shotgun that was willed to him. As far as I know, the shotgun has spent he last 30 years in my uncle's safe. Prior to that, I believe the gentleman that left it to my uncle was the original owner. The original owner was an avid outdoorsman and hunter for decades.

I've read up on some of the introductory info on the forum, and that's been helpful. Mechanically, the shotgun seems to be in very good working order. It locks up tight, triggers and ejectors seem to be in good working order (from my amateur inspection). There is a slight wiggle/flex in my palm around the trigger guard when I open the breech. On the right side, it looks like a screw is protruding out more that it should be. The bores are dirty/dusty but look good.

From what I've been told, it was the original owners primary bird and rabbit gun for the better part of 70 years. The stock shows alot of use. All the original finish is worn off. There is some surface rust on the barrels due to the finish being warn off, but I don't believe any rust has severely compromised the shotgun.

My questions are:
1. Is the buttpad original or is this most likely a cheap replacement?
2. How do I determine the choke of each barrel?
3. Given it's a Trojan, and was heavily used, is there much collectors value?
4. I'd like to preserve and protect the shotgun as much as possible. To that end, is re-finishing the metal and wood an option? How much, ballpark cost, would it cost to re-finish by a professional?
5. Is there a gunsmith in Virginia that could examine the shotgun?
6. Would shooting it semi-regularly be ok, or is that not recommended?
7. What else should I be asking or need to know?

Thank you!
Ryan
