I have found in my collection of stuff 3x NOS 1981/1982 CR250RB/ CR250RC head gaskets, and 4x NOS 1982 CR125RC head gaskets, plus a heap of reed gaskets to suit both and 2 NOS clutch cover gaskets to suit the 250, and 1NOS centre case gasket to suit the 250 also. If anyone would like these $10 each plus post at cost for the head and clutch gaskets and you can have the others for nix.
