I somewhat recently bought two old p37 pouches. Sadly I didn't take any before pictures, but I will describe them as best as I can. They were the standard MII/MIII basic pouches in khaki. Over the khaki was a lot of green blanco which I assume was dutch. I couldn't really get the pouches clean so I decided to restore them. As a replacement of the somewhat rare blanco I used olive green shoe cream. It was worked in with a paintbrush with short bristles. I got most of my info from Blancoandbull.com
I like how the colour has turned out, somehow there is a bit of a difference between the two pouches, but it doesn't really show.
In comparison with an original blancoed strap the colour matches well enough, a bit more green but assembled this wouldn't make a lot of difference.
Here a picture with the original khaki still inside the pouch.
I think it makes a good addition for my post war webbing set. What do you guys think?
