Calling All Trek Experts
I am looking at what appears to be a pre 1980 model (screwed head badge etc). Everything seems to make sense but I'm confused by the serial number. It doesn't appear to be a valid number. Furthermore, compared to photos of other TREK's around the same era, the font and spacing of the numbers/letters just doesn't jive. Anybody have any ideas?
Serial Number = NA40?334. (?=either 0 or 9)

Does it have Trek castings on the seat stay caps and anywhere else?
It doesn't have the same format or font as the 1980 SN. Nor the post 80 or the Japanese numbers on the seat tube.

Does that SN/stamping look familiar to you?

Is it a 21" frame?
A. Serial numbers beginning with M or N (41X and 61X bikes or frames) seem to have a different meaning for what normally is the year digit. The year digit is the fourth character in the number. In the 50 M and N serial numbers that have been sent in by owners, the year numbers go from 0 through 9. The remaining part of the serial numbers seem normal.
According to the brochures, Trek did not make 41X and 61X bikes or frames during 76, 77, 78, and 79 and also not in 83, 84, 85, 86, 87, 88, or 89. These serial numbers apparently do not follow the year convention used for other Trek models. It is likely these frames, SNs beginning with M or N (Models 41x and 61X), were contracted out or were made in a separate Trek facility, and were given the old serial number form so as not to interfere with the sequential numbers being assigned by Trek in their main shop, which began in late 1980.

Ok. That looks like a Haden "Europa" fork crown. Assuming that is the original fork, we used those on 7nn series frames; Reynolds 531 throughout. Any pictures of the dropouts?

From the serial number pic, to me first letter looks like an H, which would make it a 710. Of course could just be the pic quality, you obviously have a better view. Tim

Thanks.
So that would make the first character in serial an "H". None of the other digits seems to follow TREK's convention. Any idea why that might be?
