m-66single shot 3inch410 shotgun
The Ithaca model 66 single shot shotgun that was made from 1963-1978 was offered in 12ga,20ga and 410 gauge only.
yes it is a single barrell
We need more info. Is the single trigger selective or not? Does it have a vented rib and/or automatic ejectors? How about a beavertail forearm? The first single trigger used by Ithaca wa made by the Infallible Trigger Co. and was offered after 1914 in the Flues variation. That was replaced by the New Ithaca Double in 1926. In both variations, Ithaca produced 8 different grades, which all have different values. And in every case, value is completely dependent upon original condition. In short, your shotgun, in working order, is worth somewhere between $100 and $40,000.
The Ithaca Model 37 was first introduced in 1937, and has been in continuous production since. See www.ithacagun.com for more history, and the current versions of this venerable shotgun.
Assuming you mean a top break shotgun, there were several models, prices will vary. For a single barreled top break, about $70-$75
Double barrel? Single barrel? Model? Need more information in order to be able to answer.
That really depends on the condition. Take it to a gunsmith or appraiser or go to auctionarms.com to get an idea of what they are selling for.
what i did to get an idea on what it "could" be worth, is to look up online stores that have them, and compared mine to them. they have prices listed so i guesstimated mine.
