Wes, thanks for your response here and on ECJ5. Here's what I posted over there a short time ago.
I know that all this may not be interesting to very many, but for those who enjoy figuring out the little mysteries that come with the stuff we drag home, read on.
While crawling around under the trailer this afternoon I noticed that the number on the back of the right hand backing plate ended in an "L" and the number on the back of the left hand backing plate ended with an "R". So, I went searching for pictures and found some good clear pics of Bantam military trailer axles. Whoever put the hubs on my trailer put them on the wrong sides, so they are upside down. The brake levers are on the bottom, below the spring, instead of on the top, above the springs. With the levers on the bottom, the brake cables could not be run to the levers.
Since this trailer would never have brakes, this didn't matter because no brake cable would ever have to run to the brake levers.
This could have been done at the factory. I understand that the civilian trailers were often assembled using surplus parts. Maybe my trailer was made on the day someone opened a box full of surplus brake drums.
Or, as Wes suggested, maybe some p.o. had a set lying around and put them on.
May never know which it was, but, I've had some fun figuring this out and learned some things about our new trailer too.
Now, what about those big ugly wheels? I haven't found any pictures of anything like them on other military trailers. Looks like someone on a budget robbed some implement wheels for their trailer.
As for the lunette, it's a big one. I read that the Bantam lunettes were thin and the later (M100?) lunettes were thicker. So, again, someone on a budget bolted what they had to the trailer.
Trading material? Maybe. Cliff over in Pocatello has already spoken for the lunette, and he's got good stuff to trade for. But I kind of like it, especially since the trailer came with a pintle on a stinger. I think the lunette stays for a while.
The wheels? They've got to go. It's a Bantam trailer, not a hay wagon.
I've got a picture of the back, as soon as it flies from phone to email to photobucket, I'll add it here.
Here's the tailgate picture. The OD green under the current paint is showing through along the top edge.
