American gun-synchronization E-4/E-8

[bearoutwest]

Hi All.
Can anyone point me towards some information on the E-4 gun-synchronization system used in the P-39s, long-nose P-40, Allison-engine Mustangs, Brewster Buffalos, SBDs, etc? Drawings, photos, weight information, etc? There doesn't seem to be much on the net listed under the E-4 (or the later E-8) designation. Perhaps someone has come across some details in an engine manual?

Regards, ...geoff

starting on pdf page 184 and following there are some drawings and descriptions of the various parts.

Thank you.
Very useful weights and drawings - it ties in nicely with some general notes and comments I'd previously gathered.

Though I can see that I'm going to be severely sidetracked in looking for some of the other volumes - eg. Vol 1 on Turbosuperchargers.

Thanks once again,
