JohnM:
I would venture to guess that it is a 360 Express 2 1/4" (9.3X57 or 9x57-NOT Mauser) with 118/35 gauge - 0.341". The brass with parent headstamp(30-40 Krag) can be purchased at Dave's Buffalo Arms(www.buffaloarms.com - 360NE214) and are easy to reload. I have seen them cut down from 9.3X72R but I wouldn't ruin RWS cases. If the length of pull is adequate, I'd buy it, use it and think about restoring the gun after that. Shotshells can be purchased from RST or Polywad. If the lands and groves permit, purchase some Hornady 200gr #3510 bullets(or something close to 193gr) and away you go.
Kind Regards,
Raimey
