There's a Bosch Top Precision one that Axminster sometimes stock that's 165mm with the same bore as the Mafell/Festool, I use one now as I've been meaning (for months) to take my blade to the tooling place in St Philips to be sharpened. It's also a similar kerf to the Mafell stock blades too - albeit 5mm larger in diameter, but it clears the housing and works perfectly.
I haven't found anyone else who stocks it either.
