Impossible to find item!

[G8GQS]

This one is really difficult. I have a Vinten elevation unit as per the picture. it is missing the handle and worm gear that dives the column up and down.

I do have all the other bits and it would be nice to complete it. This all part of a heavy duty tripod system for big TV cameras.

Apart for all the other wants, like vintage cameras this one is to put a vintage camera on.

Thanks for looking!!
