Thanks to you both. He has asked me to sell it for him, I have the factory handbook that came with it- I think he shot it once with the 24" slug site barrel, the other barrel has a screw-in choke (only two slots) and ventilated rib with Ray-Bar sight and the threads have no mars- so I think he never set that barrel on the gun. I live in a shotgun only zone in lower MI, and come mid to late Oct I'll run an ad for it in the local GR paper-- (Can't sell pumpguns here on a doublegun website). I went to the 2008 Dan Schiendler "Gun Digest' redbook, he does show the M37-- but not the combo they offered- both in Featherlight with 2 & 3/4" chambering, and the Mag series as this one is, with 3" chambering- I want to get him a fair market price for this "combo" and the code printed tag on the handbook specifies this is a combo "package"-- Gun is 99% as new- recoil pad and "ringed" corncob style forearm--
