Default Socket for mounting B4/5 valve at 90 degrees ?

I've recently come by this socket which looks as though it's designed to mount a B4/5 valve oriented at 90 degrees to the usual direction. Did it have a particular use or was it just a fairly common thing back in the early days ? If it does have a particular use and if someone is looking for one then I'll put it up in the Sets and Parts Offered sub-forum as I can't foresee me ever using it here.

Cheers

You often see them used on late 20's early 30's set where a screen grid valve is used.

The valve is mounted horizontally going though a hole in an aluminium screen.

The pictiure shours the arrangement but without a sideways holder.

The other place you see these is in small portable sets where they have tried to make the sets "thin"

To achieve this they mount the valve sidways. I have seen sets where the valves are on a hinge and can be rotated through 90 degress as well

Thanks Mike, I'm much informed. Given that it's not truly strange and therefore only useful to one or two people I'll probably put it on the bring-and-buy at the NVCF.

Cheers,

GJ

Here's one from the Bulgin catalogue of 1936-37, a standard valveholder mounted in a metal bracket, said to be useful for the purpose mentioned in #2.
