OK, thanks for your time RK.
No worries, but this is weird.
About three months ago I temporarily stored a coupld of bike sin my loft (for security while I was away from home).
Disaster, when I retrieved said bikes, including the SBDU, mice, yes mice, had nibbled my still pristine white Monoplaner hoods.
That's how I discovered they were unobtainium, but I did source some NoS black ones - not ideal as they are not quite the quality of the white ones.
I HATE mice.
