Twin Coils Identity Sought

[hddennis]

Picked up these twin coils today and would like to know what they fit. Quick search turned up the number 1854015 fits a 1934-1937 Cadillac V16. This set hs the number 1854011 on the diecast bottom which I think might be a Delco number so maybe this fits an earlier V16 >

 

Thanks for any help,

Howard Dennis

As a V16, would it also have a dual distributor cap, one for each bank of 8 cylinders?

[m-mman]

On a multi cylinder engine it is typical to use dual points and coils and operate the ignition as a six or eight cylinder (times 2 = 12 or 16) 

 

As I understand it to not use this design doesn’t allow enough point closure time (dwell) to saturate (charge up) a single coil and produce a quality spark.

1854015 is the part number of a single coil and not of a set. It was used on Cadillac 12 & 16 (2 ea), Pierce-Arrow 12 (2 ea) and LaSalle 8 (1 ea). It was also used as a replacement coil on other applications.

Thanks Peter R. for your response. I got the number off the diecast housing. 1854011 is cast in raised numbers on the bottom of the casting. Does your book show the number for the complete set of coils with mount like I have?

Chilton's 1942 book lists a pair of 1854015 coils for Cadillac V12's & V16's 1934 to 1940 

Maybe "1854011" refers to the casting mount.

Thanks for finding and posting this. I came to the same assumption but am hoping somebody has a Delco parts book that tells exactly what this setup and "1854011" fits.

When it rains it pours.   I just posted the following thread for the same coil pack.

Does anyone on this forum own or have access to the later V16 Cadillacs? Would it be possible for them to check and see if those use this type coil set ?

 

Appreciate any help.

Thanks,

I asked my buddy with a 34 V16 to check, he said that they looked like high-performance a Packard to him.

Don't know what else these may fit but thanks to another poster I now know these were used on 1938-1940 Cadillac Series 90 V-16's.

 

Thank you all who responded with help and suggestions.
