Dear all The US Army produced a series of "Ordnance Field Service Technical Bulletins" providing additional technical data for a whole range of subjects during ww2 (and beyond). I am interested in any for the WW2 Tank, Medium M4 series of vehicles (Sherman). As these are new to me, my library stands at only these titles TB 752A-1 - 3 INCH Motor Carriage M10 Sighting Equipment TB 757-2 - Tank, Medium, M4A1 Does anyone have any of these specific to the Sherman Tank and derivatives (ie M10) please? If so what are the titles. Though I like originals in the collection, subject to the content, a good scan for the data may well be all I need. I am specifically interested in anything for Tank, Medium M4A4 to support my restoration project. These Technical Bulletins contain information either not held in the manuals, or re-written to make easier understanding. Many thanks Tim
