I recently came across this manifold for a later dommie, cobbled up with an adapter plate for the earlier manifold.

I bought it purely for the Concentric (26mm), which (hopefully) is jetted for a 500 dommie.
Fairly neatly done, although the order of assembly might be critical (?).
Not a terribly matching flowline, although turbulence is good ??

Anyone seen anything like it before ?

Looks like the one on my 60 88/99 but with home made adaptor to suit the other head mounts. If it fits what you have then can't see any problem. Also possible that its been made to fit the DD head. If used in hot climate would benefit from the phenolic ? insulator at the carb. Equally in a very cold climate a carb heater as freezing up has been a problem on mine.

I was surprised to discover that the flat adapter plate was steel, not alloy - it has been satin chromed.
Looks like the real deal. The copper wire is to retain the (loose) screws.

I'm familiar with those dommie manifolds Bob, the Model 7 dommies had them right from the start.
BUT, this one turned out to be a Triumph item. The E2913 number gives the game away,
and identifies it as off a 6T preunit Thunderbird. Its wider than the dommie one - and needs to be,
to reach the horizontal stud pattern of the later dommie heads.
6T manifold up top, dommie lower.
