Belgian wartime officers cap?

[stekker]

I've got a reply from this collector:

The date of such Peaked caps is quite difficult.

Wartime and pre wartime peaked caps usually had a coloured band below the rim, but beware also post-war caps sometimes had a coloured band. (up to 1950)
Certain units such as chaplains had no colour piping under the roof edge.
Fabric texture en colour can't really date a cap because they used very much varieties of fabric pre-war and after-war.

My personal idea about this kepi: this cap was made between 1950-1960
My opinion is based on the fact that the phone number has 6 digits. (3x2)
My opinion is not the one and only truth, but it is my idea on the basis of years of experience in the collection.
Hopefully you can do something with?

Great help indeed! Quite interesting to learn about this, thank you very much.

The phone number on the address is the sort of information that I would use to date a cap along with other details if it was British.

!950's is a bit later than I would have expected from the form of the peak, but that is comparing it to British examples which obviously does not apply here.
