One of those manuals is very high on my wants list.  I've
had my RT-45 powered up, interesting set.

I have an incomplete GP-3. Just the transmitter and a couple of
tuning units  No control boxes or mounts.

Serial number in the high 400s. An interesting thing about the set is
that the nomenclature tag on the front of the transmitter has had its
serial number and contract dated removed. The system plate on the
top of the transmitter only had the contract date blocked out, but
the serial number remained intact.. The plate on the tuning unit is
intact, and carries a contract date of  February 1936.

A few differences between the GP-3 and the later GP-6 or 7. Slightly
different front panel layout, different parts layout internally, and the
tuning units are not interchangeable between the earlier and later sets.
I have no documentation on the GP-3, so can't comment on any
circuit differences.
