pkhammer Posted May 26, 2020 Share Posted May 26, 2020 The tag on this eight cylinder distributor has Hupp and Marmon?? Any ID help would be appreciated. Thanks! Link to comment Share on other sites More sharing options...
Peter R. Posted June 5, 2020 Share Posted June 5, 2020 This is a 8 cyl. Atwater Kent distributor. Atwater Kent distributor RA-11050 was used on the 8 cyl. Hupmobile Model E of 1925. Does it say RA on the tag? Marmon did not use Atwater Kent distributors. They used magnetos up to 1919, Delco distributors from 1920 to 1926 and Delco-Remy distributors from 1927 until the end in 1933. Link to comment Share on other sites More sharing options...

Matt Harwood Posted June 5, 2020 Share Posted June 5, 2020 The '30 Marmon Model 79 we had used a Delco-Remy distributor. Link to comment Share on other sites More sharing options...

Peter R. Posted June 6, 2020 Share Posted June 6, 2020 .....the above Marmons are all 8 cyl. models (6 cyl. models were phased out in 1926). 1920-26 Marmons (6 cyl.) used Delco distributors 17000, 17022 and 17047. The distributor was an integral part of the generator (ignition-generator). By the way, Delco-Remy distributor 658-C was also used on 1929-31 Roosevelt and on some European cars such as 1927-29 Horch and 1928-29 Stoewer (two German car makes). 1 Link to comment Share on other sites More sharing options...
Dandy Dave Posted June 6, 2020 Share Posted June 6, 2020 One mid 20's Marmon I worked on years ago had overhead valves and twin ignition if I remember correctly. One distributor with 14 towers to put in wires. Two coils and two sets of plug wires. It was a 6 cylinder. Dandy Dave! Link to comment Share on other sites More sharing options...
padgett Posted June 6, 2020 Share Posted June 6, 2020 Dual ignition was common in race cars and airplanes back then. Corvettes had dual points into the 60s. Link to comment Share on other sites More sharing options...
nickelroadster Posted June 7, 2020 Share Posted June 7, 2020 To Dandy Dave. The Marmon with a dual fire would be either a 1926 D-74 or a 1927-8 E-75. This was not just dual point. It was two spark plugs per cyl. and two completely separate ignition systems. 1 Link to comment Share on other sites More sharing options...

That was one huge pig of a gasoline sucking engine. About like my Cat model 12 Gas powered Road Grader, which is only one of 56 built. Thanks. Dandy Dave!

Peter R. Posted June 7, 2020 Share Posted June 7, 2020 According to my books the twin ignition was used on 1925-26 models 74 and 1926-27 models E-75 using Delco Ignition-Generator # 319, which carries Delco Distributor # 17047. Link to comment Share on other sites More sharing options...
pkhammer Posted June 7, 2020 Author Share Posted June 7, 2020 FYI going to list this part on ebay tonight. Link to comment Share on other sites More sharing options...
nickelroadster Posted June 8, 2020 Share Posted June 8, 2020 All the info I have is that only the 1926 D-74 and the 1927-8 E-75 had the dual ignition. E-75s were not made in 1926. I guess we are kind of getting off course of the original queston. Link to comment Share on other sites More sharing options...
