OK, here's one for the real paper collectors.

Looking at the Baldwin stress calculations on a drawbar. I have the CD-ROM version of the scanned BSP sheets, and darn it, it's TRUNCATED on the far right edge, you can't see the full formulas that are on there. Sheet 14-13, Max set allowed unreadable, and draw bar pin formula unreadable. Sheet date is 6-13-47

If anybody actually has an original paper set out there, email or PM me, I need to see that sheet in its entirety. Camera shot would probably do it.

The tender you save may be your own.....

Fresh full scan, although the book copy is also cut off. The max set dimension does appear to be 3-1/2.
