Hi Chris - indeed the one tank has two square cutouts as you suggested - one longer than the other. I also noticed that the fuel cap is further back than the WD one. Not really dented though? You've obviously come across one of these before.

I'll put a wire brush onto the red tank to see what's there.

I found one - 17423. Now this came with a matching frame/engine machine 223** from contract C/S 1546. I need to pull another tank out, but I know that that came with a post-war CO, so I'd be surprised if it has a number. Another (with traces of army green evidence) has none. Another tank I have just noticed has a cutout under the tank on both sides of the central saddle. Any idea what it's off? 

Thanks Ron. Methinks I shall stop searching in vain!

Cheers Chris! And you say that it is stamped? I have a few tanks I must go and look at and see what transpires. I seem to recall that there were date stampings on panniers as well, but I've never been able to find anything.

Where exactly on the tank underside would the marking be? I need to check my ones.

W.r.t. the carb mixing chamber, several machines had a mixing chamber number like 276/014R as you mention too. The Triumph 350 ex WD was one of these. The Panther listed this as well - as did others. I've no idea if this is of any relevance, but it's all I can come up with. Possibly a corruption of this? M20 WD had the same mixing chamber number as well.

Whew Ron - even the motor painted!
