Yep, appears to be a 70s or 80s vintage Model 10 in a high grade. Though on a negative note, I notice about this seller:
1) they are running about 90% positive feedback - awfully low for a gun dealer
2) They charge $60 shipping (costs $15 tops for an FFL to ship a gun USPS anywhere in the country)
3) They didn't disclose the barrel condition, and didn't even know how to measure the barrel length (they are off by 3/4").
Not the most stand-up seller credentials, I must say. The gun is worth $300/325 I'd say. So with the shipping, your transfer fee, etc., even at the current price your overpaying by $25, unfortunately.
