What wheel is that?

Hi,
Can anyone help me identify the following wheel fitted to my suspected 1950's home made van.
Its a 16 inch by 6 inch.
I had a second hand tyre fitted to get the van's bum off hte ground and the tyre guy spotted that the centre of the rim in not flat (had been warperd from abuse apparently)

Cheers
Chris

Mate I knew someone here would know.
I guess the damaged one can't be fixed safely so may well need to call that offer in..

So now I'm wondering what age the van is..
