72 exhaust manifold

["Erik Brzoska" <mowog77@hotmail.com>]

I have an exhaust manifold that I have cleaned up out of a 72B.
And there is something that is puzzling me about it, it has a oval 
embossing on it that says something that is difficult to make out.

It almost looks like it says BURLEN. I know Burlen fuel systems makes 
stuff now, but did they make parts for MG for production as well?

The exhaust header is in really good shape and has all the regular 
markings, ie. MOWOG and some numbers.

Anyone got a clue?

TIA,
Erik.
