M416 trailer: were there Magnesium wheels on the early ones??

[nealseale]

I have a 416 Serial number 160, date of manufacture 28—8-62.
The previous owner sold it on ebay and I noticed several comments after the sale saying the wheels were worth the price I paid for it because they are magnesium. well, I have no clue how to tell but they are not the same as regular m416 wheels, or off another vehicle,and are not metal as no magnet will stick to them. Yet I’ve never heard of this, Any one have an answer or a place to refer me as I have not had any luck so far.
Thanks for reading.
I’m new to this so I’m trying to post pictures.

Magnesium wheels came on early M151 Mutt 1/4 ton trucks. People that are restoring these vehicles desire these wheels as the Army started using steel wheels, and these got replaced. I personally don’t think 416s came with those wheels but I was not there in 1961.

wow this is news to me .. Had driven and been around many M151's, A1's and A2's during my lengthy service .. Never saw no other than the typical round-hole steel rims on mutt-related stuff .. this is very interesting and making me want to re-visit old pics etc

They could be Mighty Mite wheels, they are interchangeable bolt pattern and size wise. Mites had magnesium wheels for light weight.
The M416B1 was the specified trailer for the Mite, but I don't know enough about the history of them to say whether they always had magnesium wheels.
