panoramic head FED

All greetings!
Recently there was such an interesting FED tripod with a panoramic head.

I have a question. When those tripods and heads were made ?

If you look at the logo, it's post-war.

Yes, logo on panoramic tripod is postwar.
But logo on tripod is the same like logo on some lens caps on FED NKVD.

The clamp itself might be prewar, and the head with a new logo is postwar, so perhaps the head was a separate accessory that was added to the clamp later.

Yuri you are wrong. In pre-war supports, the inscription of the FED differs from the postwar ones. It is slightly smaller in size.
Yuri, if you look closely at the casting of a tripod with a panoramic head, you will see that it does not look like a serial tripod. To make it more clear, you need to take an ordinary tripod, unscrew the head and compare the ending.
They have nothing in common! So we will look for information further.

observe also the head is mounted upside down!
