Tinker:
I did find the listing and have the following thoughts.
The price is at the very far end of acceptable. In other words, I think it is overpriced . Then again, it is quite nice for a pinfire. Most that we see are in far less condition. The case helps as well.
New pinfire brass and loaded shells are now available (reasonably priced) making it a better deal than a couple of years ago.
A gun. as this, would be at home at a Vintagers event and lots of fun on a gentle hunt for birds.
We each have our own point of wallet pain when assessing our toys.
Maybe a good look at this would be the analagy of comparing 20 fillups of gas for the truck and a fair price for this gun.
Best,
John
