Collins & Unknown Transmitters

[jtfitchSWL]

I would appreciate help in identifying these two transmitters, photographed in 1946-8 at the Army Signal Corps site in Nanking, China.  AFRS Station XMAG, in addition to a 250 watt Gates at 1540 Kilocycles (which was not at this site), also had two short wave transmitters, XMAG and XMNG. I do know that we had a Collins with a power output of 1000 watts on 4.275 megacycles. The tall cabinet in these pictures has labels that clearly read "Collins."  Is that the likely transmitter? XMNG operated on 7.240 megacycles, but I don't know the make of the transmitter or its power.  I can't make out a name on the shorter transmitter in the picture, with the sign "XMAG Short Wave" on top, and I wonder if that could be XMNG. Any information would be appreciated.  Thanks.

The short one on the right is a BC-610 of some suffix ilk.

Really popular in any military type installation.

Here's the Collins transmitter:

The BC-610 appears to be the model "E".

Thanks to those who identified the Collins and BC-610E short wave transmitters.  I have one more that I would like to have identified: the XMAG broadcast band transmitter.  My report to AFRS on 3/11/47 says only, "XMAG operates with a Gates transmitter on a frequency of 1540 kilocycles and a power output of approximately 250 watts covering the Nanking area quite satisfactorily."
I seem to remember that there was a window on the front of the unit, which allowed you to see at least the final stage tubes. I also think that the unit was only chest high, not a tall cabinet.  My search for such a 250-watt Gates produced only this one with Miss Tomato of 1946! Any suggestions?  Thanks in advance.

Gates 250-C ? (If you're asking what the one in the picture is)

Conrad seems to be very happy about the new transmitter. I'll take the tomato.

Sorry, from here I can only verify that the window is chest high.

Add some basil.

I can verify that two tomatos are chest high.

The one on the left appears to be a Collins 231, 232 series indeed.

Our club is currently beginning the restoration of a Collins 233D, a 3kW transmitter formerly used by an Airline.

Frequency range is in 10 bands from 2.5 to 20 MegaCycles.

Miss Tomato...great costume....That guy in the picture is looking at her eyes.....NOT.......No ID for the transmitter.....

That sure looks like a Gates 250 series transmitter.  I have the 250C1 which is very similar.

Here are a couple of pictures of one of my restored 250 C1's without the side molding pieces installed on the cabinet.  The molding pieces give the cabinet an art deco look with the round corner look. Gates produced this basic style with minor variations both pre-war and post war.  Both of mine have a solid door with cane metal from the midpoint down on the door that covers the 810's.  I want to make a clear door to see the tubes on mine!   The cabinet height is just a bit over 6'.

From the looks of him, I's say he probably figured out long ago that it wouldn't do him any good to look elsewhere, and that he is better off just concentrating on the transmitter.
