Mike Lutz played a Hayman 40/40 when he was in Brownsville Station. There's an ad on
this page although you can't see the detail well.
Some of you may remember Scotty Allen from early Pit days. He has a Hayman in his collection with two P pickups, not sure of the model, from the pic it is Wal-shaped.
I had read somewhere that the Haymans were all made by Burns.
