Hi Bow,

It is a mk2 so the wood is cut out for the trigger bracket, hence 2 seperate shim piles. The shims are all 6thou thick, however there are 2 on one side and 1 on the other. I dont know if this is a fine tuning attempt or someone has lost a shim, maybe several. Beer cans I have are also 6thou so I might replace with new alloy shims and just keep these to one side.

Two screenshots of me modifying my mk1 stock to a mk1/2 stock.
