M38 or M100 unidentified bolts

[Bertram]

I cannot seem to find out where these go. The course threaded bolt on the left is 5/16 of an inch and there are four.

The wing nut square head bolt is also 5/16 18NC and there are two of these.

Thanks so much for all the help on this stuff.

Your JPEG reference is not loading so you will have to give me a useable on line link to your bolt photos.

I do not believe I have ever seen that short course threaded bolt on either the M38 or the M100. They are usually found in soft wood and plastics.I have seen winged nuts and rarely winged bolts but never a winged bolt with a nut. Look at your top bows.

OK, that's good to know… I tried to locate it in ORD9amd found this part # 149535 but I can't figure out where it goes. It seems to be related to the electrical system. Thanks Wes

I could not find a part number # 149535 in my 1955 copy of the M38 ORD 9. What page did you find that number on and which edition of the M38's ORD 9 SNL G-740?
