Looks just like what I have but what ever the adapter is that is what came from the factory I talked to the guy I bought it off of and he said it was one of the wind down models just before they went out of business is that adapter still available The only problem I have had with misfires was from not checking the set screw on the hammer adjustment and it got out of whack I like the idea of the straight through that I have using percussion caps plus they seem to be a lot cleaner burning
