Spring swivels?

[GoodFooter]

Does any one make....or has anyone got and willing to sell.... the spring loaded swivels made by the unfortunately belated 'double R ' brand???
The one I have attaches to the bow perch with a thick flexible plastic coated rope type wire... with alum key screw things(replacing the ring). You then attach this to the hawks swivel via a loop leash. Not only does it really buffer any bates but also have yet to see a single tangle (hang up) of the jesses! All the benefit of the loop leash with an extra buffered swivel.

Does anyone have pictures?

Yes I do, but don't add to my reputation points - please.

Looks to complicated to me?

Looks ok for use on a block but not for the bowperch.

I think the one on the far right is the one!!! the others in the photo have solid rings which would not buffer so much..... believe me they are excellent on bows but the coating over the wire wears off fairly quickly but can be replaced as the sell it in B&Q. For a batey bird ( or any first on the bow) they totally take the pressure of the legs and the spring in the swivel is calibrated to the weight of the bird....they were made for loop leashes or normal I think, but can see why evey one wouldnt use loops as they really do stop twisted jesses....
Does any one still make them or have one they would part with???
If you want a photo of the one I have how the do I get it on here???? I have a digi camera but my knowledge stops there.
