Any idea where one would get seals/service on one of these?

Thanks in Advance

meow, i have never seen one red, any chance of a pic or two? when was it made?
powder burner?

shoot straight and speak the truth

Pyramyd Air carried the Diana/RWS R357 at one time so they may be a place to start. The Diana is almost a twin to the Gamo R-77 with only a few small differences. I wonder if seals from the R-77 would work?
