Rotax - Lucas Distributor?

[speedsters]

I have recently acquired a Rotax / Lucus distributor that I have been unable to identify, so I thought I would bounce it off the forum members to figure it out. The distributor is Mdl # DFH6A-4, Type DA11-1 Volts 12, 6465 633. Is there any way that anyone might be able to assist me in determining the various applications that used this type distributor?

A photo might be helpful here. The rotax thing suggests that it might come from a rotax engine, fairly common on experimental or home built aircraft.

I think it's a different Rotax. Rotax made radios way back when and were owned by Lucas by the mid-1900's. I suspect this is an old part.

Yup, I'm with th' Mainah on this'n.

Jesse & Coldplugs, thanks for your responses. I received an email from a gentleman in Switzerland this morning that informed me that according to his Lucas books he determined that the 1932-33 Riley used Model DFH6A distributors (counter clock wise rotation viewed from top). There are many other British made cars in the early to the mid 30's that used DFH6 and DF6A distributors but only Riley used a DFH6A.
