Oh, look at this! Phillip D’s Volkscycle Mark XX makes two, but the other is a Mark XV.
Year:197? Make: Volkscycle Model: Mark XX
The guy I bought it from said he purchased it back in the 70’s rode it for a bit and then just ended up hanging it in his garage till he sold it to me. Seems to be all original and it pretty good shape for its time. 56cm frame with 27” wheels. All original parts I beleieve shimano 600. Don’t know much else about the bike, hoping I could learn more about it through this site if possible.
