Hi Canam370,
Great to see so many people interested in your project, by the way if you take a close look at my id pic, it's the front cover of an origional 'CATALOGO PARTI DI RICAMBIO SERIE TF/1' parts catalogue sourced for me by the late great John Hall, from the Germay Importer of SWM Motorcycles Peter Schroder ( I think the spelling is correct ) who just happened to be the then President of the CTE, the FIM's Enduro sub committee. If you would like me to scan the catalogue and send you a copy just let me know, ok.
Cheers 2T_vs_4T.
