joed;saw a nice 1917 Colt New Service in a shop last week. It was NOT fooled with,strictly as issued,which is rare these days. A few wear places,dings,but probably 95% of original dull(not parkerized) finish and original grips. Bore shows a little roughness,typical from corrosive primers,but it will shoot just fine with .45 acp fmj ammo. My guess is that it was purchased by mail order in the 1960's from a distributor,and then spent the last 4 decades in a drawer! Guy that sold it to the shop owner,had inherited from a great uncle,then found his 10 year old playing with it;no ammo thankfully! Shop owner had an idea of what gun was worth but wanted my confirmation,as he mostly deals with "newer guns". Told him;ask $750,but take no less than $650; he got $700 from a guy that I told him to call,who collects military items. So,the New Services are out there. On another note; the .41 Colt,while a "big bore,is long obsolete. Other than a special run of ammo,by W-W in the 70s, no ammo produced for it for 40+ years,and ammo is $50-75 a box,if you can find it! So it is strictly a handloaders cartridge. Other than the SAA,the other guns listed are mid sized frames. It was a good short range man stopper,better than its .38 special type ballistics would indicate. Bullets are hard to get for it today,unless you cast your own. I have a 5" Army Special and a Colt SAA,that I built up from parts on a Great Western frame in .41 Colt and have shot them extensively with both inside and outside lubricated bullets;fun guns to work with,but there is NOT the sensation of firing a "Big Bore" that I think you want. Good Luck in your quest! Bud
