Wanted Friction shifter washers

[zerogravitas]

Hi folks, I bought some of these old Ofmega shifters recently, mint but sadly missing the washers shown in red in the image below. I think they are very similar to some Campag and possibly Dia Compe shifters of the time, so if anyone has any of the keyed thin washers or the others in your parts box, let me know!

Thanks.
