Hello
This might be a bit of a newbie question but here goes
. I have just bought my first airgun for a long time with the intention of refurbishing it. However I am unable to identify it, all it has on the piston spring chamber is "Series 70 Model 76 Made in Gt Britian". I think it might be a Diana as on the wooden stock there is a circular indentation very similar in size to that on some Diana's I have seen. Where can I purchase spares parts for this or manufacturing drawings if such exist and what sort of value would it be worth when done? Any help/information would be appreciated.
Thanks
