Just pulled up what I could on Kastan. looks like they only go back to 1986..way to recent for this frame. I think originally this had 28 inch wooden rims and was for a very tall person. the seat tube rises to 23 inches from crank housing . Top bar is 22 inches from seat stem to goose neck. Measurement on remaining front fork tong is 15 inches. From rear dropouts to neck is 39 inches.
