Hi, I am trying to find "A Study of E. Howard & Co. Watchmaking Innovations, 1858-1875 (Nawcc Special Order Supplement)" by Clint Geller. https://www.amazon.com/gp/product/096688695X/ref=dbs_a_def_rwt_hsch_vapi_taft_p1_i0 It has been extremely difficult to track down a copy and I am hoping that someone might be able to help me. The supplement is out of print and no longer available for purchase. I have contacted the NAWCC and other recommended sources but am still having no luck. I'm grateful for any assistance. Thanks!
