Gang,

Hey, I picked these up at an estate. Never seen them before. All anodized aluminum (blue and gold). While the box is cardboard, the _partitions_ in the box are laser cut wood. These are brand new. Only the nose retract was taken out of the bag the others are still sealed.

The are air UP, spring DOWN. But do not look like any SpringAir gear if have seen or could find on line.

Some measurements:
- blue mount plate is 1.25" x 1.75"
- gold cylinder 2" x 9/16"
- wire strut 3/16 x 10"

There's not a sticker, decal, or any indication of manufacture anywhere on these. Even the instructions don't say.
Any ideas out there?

Thanks for any help.
