I watched this listing on GB. https://www.gunbroker.com/item/971170023

It certainly seems to be a Style 1 Spiegel EG. Rory's book lists the Style 1 being in the serial number range 359000 - 377500 (1937-1938). It also lists 1936 production as starting with 351001 and continuing through 359800. I asked the seller for the serial number of this rifle, and he says it is 352310. Unless this receiver was finished late, this would indicate an earlier start to Spiegel production of about 9 months. I'm curious if any of you who keep data have information on other Spiegels that appear to have been made in 1936?
