This is a first-generation copy of an armament manual for a 109 model which I was unaware even existed... a Bf109C with a Jumo 210G, and featuring two outboard MG-FF 20mm cannons in addition to the 2x MG17s in the cowl.  There are 16 pages total in this manual, which features diagrams and technical data (all in German script, I might add... this may make it somewhat tough to read for some).

Click the icon below to go to the manual... you can click the RIGHT side of the page to advance to the next page, and the LEFT side to go back one page.
