not much meat to the breach end of those barrels....would have to be fitted to a 28ga or true 410 sized frame, not a 20 or 16ga....Im sure if the seller could of found a frame/gun to fit those barrels to he would of.....so unless sitting around looking at a flues stamping on a barrel lug is what floats your boat I see little value....and for sure not anywhere near $3500...and by saying the barrels were all set to fit to flues 28ga....makes this seller a liar, or nut case....
