[Drake] Drake 2B schematic level

[Garey Barrell]

Kees -

The schematic you have is for s/n 6290 and up.   I have one dated 
12/4/61 for s/n 4500 and up.

The 2-B was manufactured up to s/n 12,xxx through at least November 
1962, so there may have been another revision.  I have five original 
schematics, and the above two dates are the only ones in this group.
