Early on I rebuilt M1904's stripping the trees to bare wood and having them re raw-hided. As no one was reproducing Mac's.
But the M59's were a bit different in shape than 04's and for CW renacting I wanted them correct, so I sent an original "59" to Hercules Saddle Tree Co. In Utah, to copy ,The first few came from them.
For a while I got them from "Joe" Barefoot Tree Co. in Peachtree Ga. He made them form my Original also. But he became harder to work with because there was not a huge profit, in CW Saddle trees.
Then Hercules Tree was bought out by Superior Saddle Tree Co. .
They were doing my Grimsley trees anyway, so I used them from then on.
