.... and this is what I found.....
the main bits, given that this is a small rifle with a reputation for doing 12ftlbs in .177 I was expecting a bit of preload, I wasn't wrong. A notched delrin bar and a sash cramp took care of the safety side of things and a rather odd looking
spring and guide arrangement came out. At first I thought it was a square section spring, but it was just a thick layer of moly giving the impression of round being square. I had expected one of the custom guides that John used to sell, instead a section of spring has been wound into the spring on a standard guide, locking the spring to the guide. It can't twang as there isn't much chance of the guide touching the spring.
