While perusing ebay I came across this frame, being sold as a 1974
Eisentraut:

Item # 300010402172
Although it is in lousy shape and I wasn't even sure it was an Eisentraut I was intrigued because I have spent many hours and miles following a friend on his (which he did 2 PBP's on). I emailed Albert Eisentraut to see if it was one of his frames and to ask if he would repair it. I hope I'm not being rude by posting his response but it seems benign enough.
"Based on the photos it looks like a frame I made, a Limited. I would say that it is not worth fixing and I would not do it. Usually when an old frames cracks one place it is ready to crack another. It is very strainge for both chainstay to crack.
Albert Eisentraut"
It's hard to argue with the dean of American framebuilders and I'm sure
that from a monetary standpoint the frame is a loser but he seems to
feel that it isn't worth repairing old frames with a cracked tube. Is
that a common view?
