I think that you have a very old version.
To clarify, the legs are the 3030. Attached to the top of them is a head of which you did not give a model number.
Your photos show a hole in the mounting pad leaving me to believe that the screw that should be coming through the hole is missing.
If you, in fact, have that, then you can mount any QR plate system you choose onto it.
You also have the option to remove the old existing head and replace it with one of your choice.
I have the screw, spring and the lock nut, but I am missing the small circlip that holds everything in place. If I can get the right QR clamp I don't need the circlip which is why I wanted the QR. A circlip pliers and pack of rings will cost me nearly as much as a QR.
The only marking I could find on the unit was Bogen 3030. There is an identical one on eBay with original box at http://www.ebay.com/itm/Bogen-3030-tripod-heavy-duty-with-head-approx-70-tall-original-box-vintage-/141965189770?hash=item210dc8e28a:g:-FEAAOSw3mpXFtCI
I will investigate taking the old head off and replacing with something more modern. Don't be surprised if I come back looking for more great advice on that process.
Thanks to all.
