Looking for an unusual size of stainless tube fitting...

[Sea Change]

This winter I'm going to chop down my wind gen pole and use it as part of a re-designed solar panel support. Ideally I would get the two tubes welded together but I'm in the US where labour rates are through the roof.
All I need is a tee fitting, but it's an unusual match of sizes- 42mm on the bottom and 30mm on the cross piece. 316/A4 preferred, 304/A2 if I have no better option.
Any suggestions for where I should start looking? A quick google didn't turn up any leads.
I'm back in the UK over winter so I could possibly get something welded up while I'm home, but it would surely be easier to get something off the shelf, if it exists.

What lengths of tube do you need If they are short lengths they can be cut and welded back together.

The 30 mm o/d can be cut down from 32 mm o/d and the 42 mm cut down from 52.

I do this all the time with tube to fit inside 32 and 52mm handrail

Find a decent stainless welder who could do the job in 316

I just need to make up a tee, so as you say it could be welded up from two short pieces of the next size up tubing.
And in fact you've just given me an idea- perhaps I can find an equal tee to suit the larger size, and just sleeve it to bring it down to the smaller size. Back to google I go...
