Father-Son Weasel Project


Recommended Posts

Hi all, 

My son Charlie and I are very happy to join the Weasel community with our acquisition of a M29 hull and running gear from Patrick. (By the way, thanks to Patrick for graciously spending time with us and filling us in on Weasel lore!) We have just begun tearing into it and cleaning it up for restoration. We absolutely love it!

Some quick initial and I think interesting observations.

The tag number is 2003, which according to the appendix in David Doyle's excellent book, Images of War, M29 Weasel, which is the first unit of a lot of 100 added to an initial production of 1,000 units under contract 271-ORD-4727. 

There was some discussion with Patrick about the "fender flares" and whether they were added on after production and not actually original to the unit. There are sections of "fender" that are obviously riveted on and not appearing at all to be original. However, other sections look to be welded to the side of the hull. Upon close inspection of the welded sections after some stripping of paint, there is a layer of zinc-chromate primer such as what would be applied in the factory. This leads us to believe that perhaps the "fenders" are indeed original to this unit. It is also interesting to note that holes for the lower bolts of the parachute brackets are underneath the welded "fenders". Could this mean that the 100 units of the contract were transitional units between the "non-fendered" M-29s with parachute brackets, and the "fendered" M-29s with no brackets? 

We are just newbies at this so maybe somebody out there knows better.

Another item we discovered was a tag on the differential from a repair shop in Lyon, France dated March 1957. Was it a repair shop serving a US Army unit before they shipped it off to Norway?

Finally, regarding paint, we have been trying to carefully strip off paint layer by layer in search of any markings that may identify units that may have operated this vehicle.No luck so far, but we have found a layer of what appears to be a white and brown camouflage near the top of the layers. My question is what have you guys seen for paint schemes on Norway return vehicles?

A quick note on photos:

Photo 1 shows a joint between the riveted section of "fender" and welded section. Note the zinc-chromate primer on the welded section.

Photo 2 shows Charlie cutting off the riveted sections

Photo 3 shows the two lower bolt holes under the "fender" where he removed a riveted section and you an see the third hole under the small section of welded "fender"

This is just the start of the fun for us and again many thanks to Patrick for helping us get started and for this excellent forum!

@DonM I am by no means an authority on Weasel production changes but when you mentioned the 'Zinc Chromate paint' found under the track skirts and also looking at the how the skirts have been fabricated and welded to the hull, I would hazard a guess that your hull may have gone through a rebuild in the 50's by for example, the Letterkenny Ordnance depot.

Congrats again Don & Charlie.  I am really happy to see this machine in your capable hands.  Can't wait to see it running and driving!

Very interesting about the side skirts....those do look like traditional factory welds on the side skirts.  Maybe your Weasel was indeed shipped with 20 inch tracks.  @Jim Gilmore should be able to help us on this - he is slow on his responses, but I will see him this weekend at the Gilbert, PA Redball Show and will make sure he jumps in here.

Thanks again and welcome.  Be sure to post lots of pictures.  We all enjoy seeing the restoration process.  I am a few weeks away from getting back on my T24 - starting with the engine build.  Looking forward to it!

Thanks OZM29C!

Is the "serial number" referred to in the bulletin the same as the "hull number"? Our hull number is UST-24-2003 but the serial number plate is odd, it has "1003 AND UP" for the serial number.

Here is a photo of the two plates.

@DonM There are learned Weasel scholars out there who can better offer advice regarding Weasel identification numbers however I can say for sure is that your ORD plate is a reproduction but your hull tag appears to be OEM. The serial number stated in the documentation is taken from the ORD plate positioned on the bulkhead behind the drivers head, not the Hull tag located on the upper right bulkhead in the rear compartment. Could I suggest that you have a dig around the rear bulkhead behind the driver as you might just be lucky enough to find a USA number. See position in the attached photo.

One last thing, this production change list is a handy reference tool that might help you correlate the changes in production to your weasel;
