Special counterweight for SME 3012 S2 (early version with split counterweight)

I recently made again a special counterweight for a SME 3012 S2 (early version with split counterweight). The counterweight is matched with Decca London cartridge with a total weight of 14 grams include headshell. I manufacture those counterweights manually on a very precise lathe.

The counterweight is equipped with an original SME clamping screw, so fits the usual SME screwdriver for adjusting.
