Seriously folks, can someone offer a few tips on Dating these venerated bikes? I have always heard there is no help from the builder available. I have owned one that was used by a famous female racer (In Mr. Baylis' possession now, I believe) and am closing in on another nice one, and have watched them for years and I haven't a clue as to how to date them. I take it the Rainbow Trout and Limited are somewhat later than some( Apparently his statement that if they have the Eisentraut name on them they came from his shop or family was before the advent of the Limited model?) ? Anyone able to shed some light on this? Did Eisentraut use that distinctive A Model seat post cluster treatment from an early time? Has his lug style changed at some point over the years? Why might one before a specific date be more desirable than a later one? Anything else I should be asking?
