Hope this is not too far off topic. Did the black bikes with gold trim tank and side cover come with silver Norton logo on the back of the seat?
I bought a year old commando, black / gold used in 1973 and seem to remember the seat logo being silver but not sure. The bike I have now ( made July,71 bought in 1990 ) is black / gold but not original color had a fiberglass seat pan and gold logo.
