No reflector gunsight!!!!!

I've just realised that Mr. Revell has neglected to provide a gunsight in the kit. At 1/32nd I can't have that so I'm currently researching pics. I can find pics on a mk1 and a mk2 gunsight but so far nothing concrete on which version was in the later mk22 spit.......heres hoping I can find a pic of one and then get together the bits to scratch one up.
