Harry Adams' book "Saddle Makers Shop Manual" is still available and orders are being handled by his daughter Betty Ike. She emailed me tonight and gave me permission to post her contact info, but I hate to put it in an open forum where spammers might get it. Anyone who would like it is welcome to contact me.
EDIT
We have reorganized our company, and most people are still trying to get a hold of my younger sister Iris. I am Harry's oldest daughter and am in charge of processing the book orders now.
People can email me, subject Saddle Makers Shop Manual.
Best Regards,
Betty Ike
