Who might have manufacturered these golden oldies?

See attachments...
Specifically I'm talking about the gate mechanisms... But interested on your thoughts of the signals overall...

I believe that may be a very old Transport Products design...take a look at this document...looks quite similar...just a few differences:

Can't say about the signals overall, but the gate motors resemble the old GRS units at this crossing:

or these two in Montebello:

The last time I was down here in 2006, all of the signals had those old style gate motors.

Neat. Great info. Thanks!

Yes indeed... thanks for the info.
I vaguely remember a handful of these still in service around here in the early 80's before CNW went on their mad upgrading spree on the mainline. The thing that always looked so odd about them was that the gate never went up to 80-90%. Usually it looked as though they'd only get up to 50-60% at best, and just looked junky/klunky with the huge looking counterweight / connector to the gate motor.
