abc firefly

I have just finished reading an article in an old motorcycle magazine by bob currie about the sopwith abc
and it is titled ABC FIREFLY has anyone have knowledge of this ?.It does make sense as we have the dragonfly,gnat,wasp,hornetand of course the scorpion engine.It would sound more glamorous,WHAT MOTORCYCLE DO YOU HAVE ? ITS AN ABC SOPWITH FIREFLY.

The firm also produced a range of small stationary engines including the Firefly flat twin-cylinder engine sometimes used in British coastal patrol blimps to power radio sets.

Can find very little other information.

but during the search, i thought of the Flight Global Archive. This is every Flight / Flight International published between 1900 and 2000.

An example, is an article on the flat twin 400cc:

https://www.flightglobal.com/pdfarchive/view/1923/1923%20-%200216.html

This contains power curves, but as they are for the aero use, not sure how relevant.

there is a lot of info to search, so chose a sensible date range.

I found nothing in the 1910 - 1918 range, so then chose 1918 - 1924

https://www.flightglobal.com/pdfarchive/search.aspx?ArchiveSearchForm%24search=abc+firefly&ArchiveSearchForm%24fromYear=1918&ArchiveSearchForm%24toYear=1924&x=0&y=0

Hope it is of some use, and again, not repeat of past work.
