Early walther lg advice needed please
I've just dismantled an early Walther LG ready for re-blueing and need a bit of advice please. As this is a 10 mtr rifle I was very surprised at the amount of pre-load on the main spring, I wasn't expecting it and I'm thinking this can't be right on this gun ? One end of the spring is not ground flat so I assume this is not the original Walther spring. Do these low power Walthers have a huge amount of pre-load and if not who can I get the correct spring from ? The seal/washer looks fairly new and is red synthetic whereas I thought the originals were leather, have I got this wrong ? The other thing is that the piston was so tight in the cylinder I had to remove it with the help of a brass drift and hammer so I would also like to know whether the rule of thumb I've always used with springer rebuilds applies to these Walther's as well which is that the washer/seal should be sanded just enough so that when fitted to the piston it should be able to drop down the cylinder slowly under it's own weight, is this correct ? Thanks, any advice appreciated.
