Yes, 6061 stamped on the inside of the drive side rear dropout, so a proper Zaskar. Was pretty tough to clean up without polishing out the burnished finish. I could make it mirror like, but that would defeat the purpose of having GT's ball burnished finish in the first place.
Not too easy to photograph in the sunlight, but the pics came out ok. Frame is a rider for sure, with some chain suck scars and a dented top tube from bar swing
Once built up and dressed with proper decals, it should be a fine specimen.
Haven't seen much without it. My GT LTS has two dents, one crash and one also from the bar, but I lifted the bike and the bar turned to the frame and even then it dented.
And I know the polishing, took me hours to polish my LTS and RTS and I also did Martin's 1992 Zaskar.
But he gave me a Snickers
