jeweler:
First I guess the 1052 to be a date stamp of October of 1952; is it of that vintage? Next, the Germans didn't put the numeric value of choke on the tubes. They just noted constriction with a "crown" over "W"(Wurgenbohrung) and were also proofed/proved twice. I can't recall the min. amount right off but the only way to determine the actual degree of choke is to shoot a target and count the corns/pellets in the 30" circle making a ratio to the original number in the cartridge. For a numeric value you can measure 22cm ahead of the standing breech and compare to the diameter at the end of the tube to get the "points".
Kind Regards,
