70s Trialmaster

[mitch briggs]

Hello everyone. This is my first post. I collect vintage wax cotton motorcycle gear and have a 1970s Trialmaster which looks like its never had a label. It may have been removed or fallen off but its dirty over time and theres no shadow or trace of it being there.
I was wondering if anyone knows whether Belstaff ever released jackets without labels due to shortages. This is what my life has come to lol. Hoping for a fellow nerd. Cheers mi dears.
