39mm holesaw, where to find them?

Weird? Maybe in the land of the free, but on this side of the Atlantic it seems that 39 is a standard size. Checked with several suplliers and builders and they all come up with the 39mm when asking for a BSA bracket shell. 38 is the light variant and 40 the heavy duty as far I have understood ever since I started building.

This is where I email the BB supplier and ask what cutter they recommend using. I probably know the answer, I just want to make them sweat a bit
