Panzer Tracts No. 7-1 - Panzerjaeger (3.7 cm Tak to Pz.Sfl.Ic) development and employment from 1927 to 1941Now for the first time we present an accurate detailed history of the creation, production, and combat action of these famous tank destroyers. This first volume covers the initial attempts to create chassis specifically designed for self-propelled anti-tank guns (which didn't get into mass production) and the resulting makeshift conversions on available armored chassis that had to be used in combat. Altogether 12 different projects are covered starting with the real Zwischenloesung, Krupp L.S.K., L.Tr.Sfl., 3.7 cm and 7.5 cm Sfl., Pz.Sfl.II, 8.8 cm Flak 18 Sfl., Pz.Sfl.IVa, Pz.Jaeg.I, 4.7 cm Pak(t) auf Pz.Kpfw.35R, and ending with the rare trial Pz.Sfl.Ia and Pz.Sfl.Ic. New as-built drawings - accurate to the same tight tolerances demanded of the original assembly firms - were created for both production series of the 4.7 cm Pak(t) (Sfl) auf Pz.Kpfw.I. This 72 page book is heavily illustrated with 17 scale drawings and 67 clear/rare large-format photos.
