I'd like to see some sharper pics of the Schroder, when you find your camera: it looks like it might solve the mystery of a frameset with similar lugs that was posted to this forum years ago. Any other details about the shop in MdR: was it *built* there or were they just the middlemen?
And, I agree: check into how much a head tube replacement costs before calling the Woodrup a lost cause.
Great bike hunting!
