I hope somebody chimes in that knows a little about these guns. I have one in .410 that my wife has claimed. She hit the first 4 squirrels she shot at... next thing I know, she say's it's hers.
Mine has double beads, brass p/g cap and brass buttplate with deer engraved on the buttplate. flower and scroll engraving on the receiver. Beavertail forearm, double triggers. Mine (sorry... the Mrs.) has blued rec. instead of coin finish. It also doesn't say Dakin Gun Co.. Instead it's marked Eagle Arms, Gaspar Arizaga Eibar.
I hope you get some info on the one your'e looking into. I wouldn't take less than 1K for mine (even though I paid considerably less). There has been a 10 gauge that matches my .410 in Gunlist for $800. It's been in there for 2 years so it must not be a "hot item".
