Restoration of my Dutch Roset trailer

Post by Brinken »

Hi all.
This spring I purchased a Dutch Roset/Polynorm trailer which been under restoration.
I also purchased a new canvas top from John & Mary Worthing in Gr. Britain. I discovered that the rope for the old canvas is in one piece, while the new canvas have several small ropes.

My question is therefor: Is there a "proper way" to tie down the canvas? Did the army have any instructions for how to tie down the canvas.

Hi Jan-Olof,
You've been busy. That's a nice looking trailer! What's the history on that model?

I've not seen written instructions for roping the tarp down to the M100 in any U.S. Army manual, but there are some photos in the manuals that give clues. Ten total ropes. One rope per eyelet on the tarp, except each corner rope goes through both adjacent corner eyelets. And one rope per hook on the trailer. My understanding is that all ropes are the same length. Mine are, but I cut them that way.

I can't see in your photo if your trailer has 11 hooks on the body like my M100 does, four on each side, one on the rear panel, and two on the front panel, but your tarp looks correct with 14 eyelets.

I'm sure you've seen this and other posts in this form: http://willysmjeeps.com/v2/modules.php? ... light=tarp

Good luck!

Jan-Olof,
You might want to consider this Army-approved bow for your trailer canvas...I used a 2x6.
It's from PS Magazine #220 on page 52, here: http://psmag.radionerds.com/index.php/Index_by_issue

Hi Ron, long time no hear.
Thank you for reply and links, but unfortunately the links don't work, maybe too old.

The history of my trailer is that 4 Dutch companies (NEKAF, Polynorm, Roset and the fourth that I don't remember the name of) manufactured post war trailers mainly for Dutch army, but also for other European NATO countries. Some 70000 trailers were manufactured up till mid 70th. They all were made from original American drawings from Bantam or M100. All dimensions on my trailer are identical with what I read from American specifications.

My trailer was manufactured 1955 by the Dutch company Roset, and have been doing service in the Dutch army. When leaving the army it came to Norway and finally ended up in Sweden 2019. I purchased it from a Swedish guy in February 2020 and finalised the refurbishment last week.

I purchased the canvas tarp for a small company in Gr. Britain and it seems to be the correct amount of ropes and eyelets. It have one "J" hook on the front and one on the back and 4 on each side. I have seen a lot of photos on the Internet how to tie down the tarp and the same amount on how to do it.

The old tarp that came with the trailer when I bought it had one rope going around to each eyelet, and to me it seems easier to release a small part of the tarp when you put some smaller things in the body.

Following are pics on my "equipage".

Jan-Olof,

Can you tell us more about your trailer? I have many questions starting with:

1 - Is it a Roset or Polynorm built trailer? The trailers are similar.

Here's a link to good photos of a Roset 1952 unit.

Here's a link to photos of a 1954 Polynorm.

2 - I see the Roset uses a canvas top with bow seems already in it for the steel bows. Does yours show the round rod stock bow sockets?

Our Army did not publish a specific rope tying directive but their applicable manuals do show them well.

You may find help with the trailer's ID and manuals on the Nekaf web site.

Hi Wes, nice to hear from you.
To answer your questions:
1- It is a Roset built trailer. The data plate says built year 1953, and the Swedish registration says built 1955.

2- Yes, the steel bows and the sockets are in place, both on my old canvas top and on the new one ordered from Gr. Britain.

I can see from your pictures in TM-9 that the M100 had already sawn corners for better fit. My corners have to be folded in from the square tarp, a little thicker but OK.

My new tarp seems to be a little too big, maybe it will thrink a little when getting wet, and it will fit better.
I include some additional pics as well.

Wes
In my search for spare parts for the axle on the trailer I have established a good contact with a Dutch guy with lots of knowledge around these Dutch trailers. He have sent me a PDF-file of Chapter 4 in the manual 1/5 TH9-6619 covering the axle and brakes. Unfortunately it is in Dutch language with just a few pictures. I can send it to you, but I have forgotten your email address.

I needed one oil seal and one rubber mask for the metal rod penetrating in the wheel house for the parking brake, but it seems impossible to find spare parts for this German made axle. I have searched all over Europe for these parts unsucessfully.
