Just lucked out and bought 2(18 drawer) cabinets with presses on both. They have all equipment and loaded with cyrstals. One of the presses looks to be metal and the other wood. From what I remeber my watch guy had a book that references the size and the crystals in these cabinets. Where can I find such a book? Also any idea on where I can find instructions of use of press? Rough idea o value? Picked it up for $75. Any advice appreciated, thanks.
