Does anyone have more information about this cartridge ?
Bottom stamped 40 avu 8d and some small stamp on the lower side ? I think 63 or 65.
But what does this number mean ?
From what i can find this is a 13 mm mg131 cartridge .
Also found that these are rare , is this true? If yes then why ?
Hoping to get some answers .
Regards
Raf
