Well spotted !!! CB250,350,CL350,SL350, some are CB450K metal ones. Enough there to make one decent set though for my 250SS
and mechanisms are the same, just different faces.
I got them all from the same source, from a guy called Barry in Minnesota. I think he was a rep for years and scoured the USA for bikes during his normal day-to-day business and just stored them in lots of trailers /containers. Then a few years ago he sold all the rare stuff to fund a building to sell parts from. Most of the plastic speedos are well below sub 10k miles. He threw in some CB500/550/750 larger ones too for free but they were not in the best of condition and no plastic 750K0 ones!
Problem now is the cost of posting from the USA and custom charges . VAT etc. Just not really worth it any more, using 'standard' shipping methods.
