Hello
finally I am assembling the Telescope and the rifle but need help.....as one of the clicker plates does not move smooth. It has a couple of friction points where the force requested to move the drum is quite more high. I believe it is due to the 3 round head screws used to secure the plate instead of the countersunk type. The other plate has the correct type and moves fine.

Can somebody sell me the 3 correct screws or letting me know where can I purchase them? The Laidlericon's booklet says BA N°8x3/16.

Many thanks in advance!!!
