i have one, pristine 1968 eroba, decals/paint/og bar wrap in excellent condition. I purchased this from the original owner who said it was ridden a handfull of times new then parked. it appears to be a 57cm i'm 6'1 & lanky and prefer a 60 cm, shipping would kinda be a pain if your not local (but hey why not). so which ever way if someones interested i can take parts off or leave them on for a fair trade, hope it finds a nice home.
the good:
altenburger levers & centrepulle brakes, simplex shifters & derailleurs (rear derailleur has 1 bad cog), ranger hard plastic saddle stamped "made in german"
the bad:
bad bb & bad bearings on og steel wheels
(photo'd not og rear wheel, front is, both have "light" oxi but will return with light polish imho)
