I recently got my hands on a couple of "mystery" gimbals, and I'm wondering if any of you guys would be able to identify them by what they look like. They're no brand name labels, or marks or serials on them, but I'll share some pictures, and some details below...

This gimbal is for a 1.5" post, has a six-inch gimbal grip with a blue anodized quick release latch. The handle is pretty long, about 7 inches. The outer bearing ring is actually silver, although it looks black in this pic. It's missing some trunion caps, as you can see in the pics, which expose the trunion bearings...i'd like to get some caps for it, but I don't know what brand this is. Don't even know if it supposed to have caps. The yoke action is smooth and fast, as are the trunion bearings. The pan bearing is smooth, but "noisy"...kind of hard to describe...it spins freely, but you can feel friction transmitted through the grip, and it makes the kind of sound a lazy susan might make when you spin it?...might it help to know the make of the gimbal so I can properly clean/lube the bearings? Or maybe it's shot?
This gimbal is also for a 1.5" Post -- the grip is 4" long or so, and has a kipping handle on the bottom for a lock. The locking part can be unscrewed from the grip itself. The handle looks like your standard size handle, and is textured with an aggressive knurling. No rubber O-ring. but there is a space for one. The trunion caps are sqared off, and without spanner tool holes. You basically just twist them off. I took the gimbal apart, and on the pan bearing, there are some manufacturing marks as follows : JAPAN/KOYO/6809Z...I'm assuming this is the make and model of said bearing...perhaps a good clue to what make and manufacturer this gimbal may be? This seems to be the better of the two, as all movement is silky smooth and silent.
...and that's all I got! Any help or advice is much appreciated. Thanks for taking the time to look through. Let me know if you have any questions or comments!
