Are these from a Mossie????

Cheeky 😉

surely a set is 12 😉

Thanks guy’s we have a set of 7 if anyone is interested…

Definitely Mossie, see similar at https://forum.keypublishing.com/showthread.php?139695-Historic-Aviation-Metallurgy-Exhausts&highlight=

Your part numbers are overstamped, in a way that would have taken a lot of effort. Somebody did not want these used in the application.
Yours is Inconel with carbon steel flange, made in Canada. I wonder if these were dropping off in service as the carbon steel rusted away, and were later replaced with Staybrite bodies and flanges, as per the Exhaust thread second sample. Somewhere will be a maintenance Amendment note for two stage Merlins saying Inconel/carbon flange stubs to be replaced with 100% Staybrite in the 1950’s….

lovely chaps.. cheers!

Mine are stamped L98 etc

Fascinating, thank you Dairwin.

Hi Peter – it looks like the first 3 letters/numbers are L98. If this is the case then yes, it’s Mossie.

Northstar exhausts are cross over type, with combined manifolds.

DAI

Being in Canada, could they be ex-North Star?

I believe so, without confirming the numbers offhand

Peter,

Here is a picture of a stub from Lancaster ED908. The different angle of the picture makes it difficult for a direct comparison. Maybe yours could be a little longer?
