In dropped a shim, but something else came out? - Help!

Hi everyone,
Been using viper_biker's guide to valve clearences (and very good it is too). Stipped down my nc30 and checked the clearences and all the shims on cylinder 4 need replacing. Got the 2 exhaust and outer inlet fine but went to get the inboard inlet shim and found it was missing. I hadn't tried removing it so can only assume it somehow got pulled out by a rag as the engine was running ok prior to this.
I searched everywhere, all over the floor, round all the castings on top (not an easy job trying to see past the forks) but to no avail. I'm damn sure its not in the cylinder as the spark plugs were left in loose and the inlets blocked up. Turned the engine very gently by hand and it spins fine, but I did hear a small rattle like it had fallen down. I've dropped the sump as much as I could without removing the exhaust and couldn't see it in there at all but did find something else (see below).
Any hints now on finding this shim? Seeing as the engine spins fine could I get away with starting it up, leaving it to idle and hoping the oil flow can wash it into the sump? Not ideal I know.
Section 2 of this is what on earth is this part?
Found it in the sump, slightly crushed and damaged on the edges its about 14mm long and 7mm diameter. I've not done anything involving parts like this so guess its from a previous owner.
