Door lock differences
 

Here are two photos showing details. Both were made in 1947 when in Netherlands Army service (one could even be yours?). They both seem to have the "humpback" (for lack of a better description) door locks.

This fourth photo made in 1946 seems to show your "first" type of door lock?

Finally made some time to work on the Otter……So off with the doors and off with all the layers of paint….thanks to the needle scaler. Minor repair will be needed on the one door. At some point someone for reasons unknown took a torch to the middle of the door. Lots of layers of paint in its life but underneath the metal is close to pristine.


With regards to welding up the torch damage. Anything in particular I should be mindful of or can I just weld it up with my Mig welder?

"if it doesn't move, paint it"
 

When it was a army running on conscripts, the Netherlands Army vehicles got copious amounts of paint applied to them "to keep the soldiers busy". I wonder if your Otter was ever fully stripped and repainted in Dutch service, or whether the new layers were painted on top of the wartime paint layers.

Have any other markings besides the "W/T" come up?
