+10 on the wow on these! My oldest bike is 1974, and amazing to see examples that old untouched.

I totally get the idea of it being difficult to sell them because of the connection to the house. I suppose if it were me, I'd keep one for sentimental connection, then sell the other two-- not for the pure profit of it-- but to make sure they got to the proper person(s) who'd fully appreciate them.

But again, wow, I look forward to seeing more of what happens with these.
