Hi Kyle.
You are right, Briggs made a crank handle to fit that pinned shaft sticking out the front of your blower housing. Your engine was started by first slipping the crank handle onto the shaft & engaging the slots in the handle hub with the pin running through the starter shaft. You then pushed handle and starter shaft/ring gear into the hole in the blower screen so the ring gear will engage the pinion gear on the end of the crankshaft. That's the obvious part to starting this engine. If you look carefully at your posted pictures, you will see a bent over 3/16" rod sticking through the top of the blower housing on the left(carb.) side. This rod is the most visible part of the compression release--the next step in the starting process. The operator would set the choke, pull the comp. release lever up and hold, and turn engine over several times with the crank to build up speed in the moving parts. After enough momentum was achieved, he would release the spring loaded lever and continue cranking until the engine started. After startup, operator would remove crank from starter shaft and set it in a handy place, open choke, set throttle to desired speed, etc. As you have already observed with your project, most of the time the handle is no longer with the engine when it is rediscovered. You might try posting a wantad in the enginads, and there are some people on the vendor pages who might also be able to help. In the meantime, you could belt this engine to a small HP motor or another small engine to try to start it. This should be done in a way that allows the belt tension to be released and the belt removed after engine has started. If you can't picture a safe way to do this, please don't follow this suggestion--there is potential here for a real tragedy if this is done wrong!! As a safer and simpler alternative,you could also take a 4' length of starter rope with a handle & wrap the loose end around the belt pulley. In any case, I'd take the belt connecting the engine and compressor off before trying anything .

From what I have seen, original crank handles are kinda hard to come by and a bit pricey when you do find one. I have made starter crank handles from mill vise handles. You have to make an adapter with a square shank that will press fit in the handle. I will try to post a picture of one of mine later.

That's a real stout looking handle, John. Adding the adapter gets the swing end of the handle a little farther away from the blower housing and starter bracing--I like that, too! I'll have to keep my eyes for some of those handles at the local flea markets.

If we tell you all the answers, how will you learn, Grasshopper?
The information you seek is available at the following site (among others):
http://www.flywheelers.com/pages/BobLearned/tekdata.htm
My guess is that your engine is a Model Z or ZZ. The build dates for this model is at the bottom of the page. You will also find lots of other good stuff about old Briggs.
Good luck & have fun.

Dont know if you already know this or not but i think you'll find once you get the ZH running, they make for REALLY fine idler's. with a carb finely tuned and the crack screw set JUST right,...you got yerself a nice low RPM idler.
