Open ended wrenches supplied with 1940's machines
I've been trying to collect a full tool kit for each of my 1940's machines.
In the parts lists the open ended wrenches are numbered:
5B780 Wrench - 5/16 & 3/8 OPENING
5B781 Wrench - 7/16 & 1/2 OPENING
5B782 Wrench - 9/16 & 5/8 OPENING
5B783 Wrench - 11/16 & 3/4 OPENING
5B784 Wrench - 13/16 & 7/8 OPENING
5B785 Wrench - 15/16 & 1 OPENING
5B786 Wrench - 1 1/16 & 1 1/8 OPENING
5B787 Wrench - 1 1/4 & 1 5/16 OPENING
5B789 Wrench - 1 1/2 & 1 5/8 OPENING
Note there is a gap between 5B787 and 5B789 !
I have never seen and example of, or seen a parts book listing a 5B788 wrench
Could anyone tell me if 5B788 does relate to an open ended wrench, and if so what size, or if the number was used for another part.
