ID HELP NEEDED on 16 cylinder distributor cap

[plk]

Does anyone recognize this 16 cyl distributor cap?

[Dave Henderson]

I can't make out the lettering,  tell us what it says please.  Is there a maker's logo? 
Some possibilities;  Nash ambassador 8, '33-'41 had dual ignition with an Auto-lite cap, also some fire engines with 8 cyl. Lycoming engines,  V16 Cadillac or, Marmon  maybe?  Or Peerless  V16 (1 prototype in '31, not likely)

The lettering at the top (at 12 o'clock) says FIRING ORDER. Now we just need to find a reference with the firing orders of various multi cylinder engines.

"38-'40 Cadillac V16's firing order was 1-4-9-12-3-16-11-8-15-14-7-6-13-2-5-10, so that eliminates those year Cadillac V16's, but leaves the earlier ohv 16 version to ponder.   
Wish I could read all of the firing order on the cap, that might also eliminate the dual ignition Nash and fire truck 8's with 2 plugs to a cylinder.

To me it is  a distributor cap for a Cadillac 452 A B C D and the 36-90 , top outlet , early engines came with a side outlet for the plug cables,  firing order is correct for the Cadillac V-16

[plk]

Firing order is   1 8 9 14 3 6 11 2 15 10 7 4 13 12 5 16

Both black and brown caps are Delco

Both are used

Black cap has a scratch or track on the inside from 1 terminal

Brown cap has 1 tower repaired by glueing the chip back in place; chip is on the inside of tower.

Open to offers

I believe the '38-'40 Sixteens used two 8-cyl distributors.

 

I've repaired interior cracks on rare caps by (1) Dremel-drilling a shallow hole at each end of the crack to keep it from propagating, (2) applying about 5 single-stroke coats of epoxy fingernail polish, coats one day apart.
