Want to Buy WTB: clean 48mm Yellow Filter with threads on both sides

I have a Canonet QL17 with a screw-in lens hood, so I need a filter with threads on both sides.

(I believe Canon sold filters with threads only on one side to go with their side-tensioning lens hood. Or maybe that was Olympus...)

I am also interested in Orange and Red filters, free of scratches and scuffs, for black and white.

Thanks

Are you still looking for these filters? I have an orange in 48mm. PM if intereested. Bill Barber

Would you be interested in a yellow-green filter? I have a nice PSL-Aico that could be yours for the P&P (about $4 from Denmark). PM me if you're interested.
