Normal metric thread description is dia X thread pitch. ie 10mm x 1.00
= 10mm basic diameter with 1 thread each mm 

Are you saying you need a 10mm tap and die with a 26mm pitch?
I don't think so, nor am I aware of any metric english/combo threads ie 
10mm 26tpi.

But if you measured 25.4 tpi you would have a 10mm x 1.00 thread.
Taps usually avaliable in auto parts stores, dies not as common.
best bet mail order from tool supply should be a lot less than $68.

>= 10mm basic diameter with 1 thread each mm 

Yup, I know that.

Campagnolo axles are 9 and 10mm x 26 tpi.  The story I heard was that after 
the war they had metric stock and imperial tools.

Got any firm(er) leads?
