Hi Tim,
Thank you for your comments. I will contact Mike to see if he can help.
Several people have suggested that I leave the bike as it is, and I am tempted to do that. I will strip the mechanicals down as the motor hasn't turned since 1968 to the best of my knowledge. The photos do make the bike look better that it really is, but its bare metal underneath, and that originality maybe well worth keeping as you say.
I appreciate your advice, having never used this forum before I am impressed with how helpful everyone has been.
If I see a 1927 Model 186 c/w sidecar, I will stop for a natter!!!!
Kind regards,
Nigel
