All scans from Chitown's digging. Thank you for posting them.

When and if you clean those rims up a bit send me some pictures for my project. The later catalogs say "aluminum finish" with blue pins. I would like to see that. let me know.

I'm not going to clean them much, but I saw a stack of some of the almost same color NOS wood rims. There were probably 8-10 of them there. He said he would sell them, but we didn't discuss price.

This is a magnification of the Yale chainring
indicated by initiator of this thread ....

Immediately - below ... is a Davis- YALE with similar chainring, but
having 26-T AND a similar 2-piece crank as on initial specimen.

And now a magnification of the Chitown literature
(posted by Goldenindian) ...... below ...

Just for grins .. let's peep the two variations
of "LETTERED'' Yale chainrings ....

post script ... I have no idea of the year Davis began production
of these.

Lovin the "Just for grins". I'm grinning.... I wonder why the variation in # of teeth of the chain ring? But 24 t vs 26 t isn't going to make that much difference. Comparing the 2 pics, the neck seems to be a bit shorter on the 2nd bike also.

Oh, Junkhunter ... your Yale is beautiful to behold.

Generally speaking .. the less teeth available in the
chainring .. the easier the machine is to pedal ...
especially uphill.

However, more revolutions of the crank are required
to go the same linear-distance .. than the same ride
equipped with a larger chainring.

Early manufacturers often gave a potential buyer the
option of a standard chainring .. or one with fewer
teeth .. providing the rear-gear stay as the manufac-
turer placed it.

In addition .. the height of the ''neck'', or headtube ...
is often in proportion to the frame size ... as determined
by the distance from the center of the crank .. to the
very-top of the seatmast.

Really diggin' this Yale !

Thanks Hoofhearted. I understand the relationship of gearing. I didn't realize it was an option at point of purchase. I also know how to measure seat post. I ride a 24" Pope frequently, even though I'm less than 6'. This size chain ring is going to make this bike a great cruiser. I have a set of 700c wheels that I built with a Model A hub. But, this hub, from what I have learned, may be a hub that wasn't named "Model A" yet. This one may be a numbered New Departure hub. I learned that from some of Wheeled Relics observations. Anyway, thanks for the great replies and pics. I enjoy them, and appreciate your time. I think this bike will be right at home here where Yale University is.

JUNKHUNTER ... am posting some fotos of machines with
insane chainrings ... not intending to do any hijacking ..........
only extending the reader's frame of reference.

If you have an issue with my attachings ... i will delete them,
if you give me notice within the CABE's 24-hour edit window.
