Does anyone know the make of this hinge. Need one. Are they still made? This one is broke.

I cant say I've ever seen one exactly like that. It looks like it was made to have a removable control surface. In that case you can still get large scale hinges from Dubro that have a removable split pin.

Thanks!

Not familiar to me either? A friend once bought an AMATEUR built kit at a swap meet.. it had square leading edges, and hinges off of we think.. a suitcase !
