1937 Flathead lost bolt... Help!

Ask your wife to take a look for it. Mine usually finds a lost item in about 12 seconds, after I'd been looking for it for an hour or two. She just hands it to me without saying a word and walks away with a kinda smug smile on her face.
 
I have a bare '37 block, so I was looking at it to better understand where the oil drain passages were in the rear of the valley. The two rear oil drain holes originate in the round cast cup area where the fuel pump push rod is located, just under the opening in the intake manifold. There are also two drains from the valley one cylinder forward of that location.

I set an intake manifold on my bare block and tried dropping a 1/4-20 x 5/8" capscrew in the opening for the fuel pump stand. I used a magnetic bolt just in case. The third time I dropped the screw in, it went down one of those drain holes by the fuel pump push rod bushing but it stuck in the passage before getting to the crankcase. I was able to fish it out from the top. You might want to check around in that area again.

If the bolt went through that passage it would probably end up in one of the two top cavities that Mart showed in his picture. They are probably pretty difficult to check with the crankshaft installed.

Good luck with your search.
 
Ok....extra pair of eyes is a good suggestion....
I have a 40 flathead on the floor so had to take a look for possible hiding places....
The oil pressure sending unit on mine is sitting in a catchers mitt of a pocket....have you tried there?
