Well it's in my hands now!
Here are a few images to share.....








and the marking I was looking for 'C' for donk52 as the builder of this pistol!





Oh, and the trigger..........well it is truly amazing, I had a 1976 High Standard Citation Target 22 that had an amazing trigger but this Model 52 takes the cake, thanks Don (donk52)
If anyone has more to share on the labels please join in! Build date??

** I am looking for an owners manual for this gun**

Does anyone recognize these finger grips as to maker by chance? They are quite comfortable actually
Also, in ink on the end of the box in the blue is 501.90? Could that have been the price of this gun at that time??

This purchase was the result of a WTB on Armslist. It was just a matter of days when the seller contacted me, said he hadn't shot this gun in a ling time and he was going to put it up for sale, he was the original owner of it! Wasn't sure if he had the original grips he said, wasn't sure if he had two magazines he said............it all came together and I am impressed and excited!
A very special thanks to the original owner for taking such outstanding care of it
