Well, that didn't help much did it? The books make it look like the same housing was used on all MA's, MB's, and GPW's. And that just can't be right because we see too many variations in the field.
Before we talk about the variations it might be handy to put a name on some of the components and features of the steering gear housing. I don't know what the real name for these parts are so I'm going to make some up. Hope you don't mind.
Now that we speak the same language, let's move on to the different models.
But first a side note. I have three slat grills. they each had a different steering gear on them. One was "F" and GPW marked, one was Ross marked with no buttress, and one was Ross marked with a buttress. ALL appeared to have been on the jeep forever. With all that paint and rust etc. etc. etc. blah blah blah they just HAD to be original to the jeep. nope. To quote one of my all time favorite hit TV shows, "One of these things is not like the other. One of these things just doesn't belong."
I believe it is just about impossible to determine if a part found on a jeep was placed there by the factory 63 years ago, or placed there by an army motorpool 62 years ago.
but I digress....
So far there are two manufacturers of Steering Gear found. Ford and Ross.
Ford will have a script "f" stamp and "GPW-35xx" ( I haven't been able to make out the whole number yet.) on the mount plate. These appear stamped or engraved.
Ross on the other hand seems to like to emboss it's name on either the mount plate or the tunnel.
FORD #1
Features: No collar, but does have web and buttress.
"f" stamped on mount plate. "GPW-35xx" on mount plate (I haven't been able to make out the whole number yet.)
FORD #2
(not verified. may just be a trick of these photos)
Features: No collar, No web but does have buttress.
ROSS #1
Features: has collar, web, buttress.
"ROSS" and "U" or omega in box embossed on tunnel. "T122983" and "PATENTED" embossed on tunnel. All appear upside down if gear is placed on table mount plate down.
"T13086X" stamped on mount plate (last digit may vary, not verified). at least one has "3" stamped on top of tower.
This is the steering gear shown in most, but not all, of the TM's with drawings and photos.
