One of my students is refurbishing a 76.2mm Tasco that may be a 15TE or a 10TE with the add-on clock drive. It came missing the serial number plate (along with most everything else but the OTA, mount, and tripod, and a very beat up wood case that had enough of the wood inserts remaining to imply that it was before the switch to styrofoam), but has the bracket and large gear for mounting a drive motor, as seen in this thread:
I've done quite a bit of searching and reading of prior threads, and although I have found a bunch about the history, and the different models of drive, I haven't found the actual specs that could be used to source a replacement motor, beyond it being a 60Hz, 110VAC synchronous motor.
Does anyone know the RPM rating, whether it is CW or CCW, the diameter and tooth-count of the spur gear? Seems like we should have that documented somewhere.
Or even a pointer to a source for an equivalent motor?
