Tophat: Thank you.
Yours is indeed a 1926. I would marry her as well.
Back to my Ace. Made in the late 70's with an SM in the serial number
according to Clawson. (commercial Series) page 220
"The Colt Service Model Ace incorporated a floating chamber invented by David M. "Carbine" Williams of Godwin North Carolina. As designed, the floating chamber was forced rearward by gas pressure, quadrupling the normal recoil power of the caliber .22 long rifle cartridge and adequately simulating the recoil action of the .45. The Service Model Ace represented a significant improvement over the earlier Ace, but both modles were marketed simultaneously."
