MPP Model 1 6cm x 6cm Enlarger

I was looking for a base board and 30mm tube for a MPP Model 1 6cm x 6cm Enlarger, can anybody help?

If you're in the UK, I have a base board you're welcome to have (it isn't an MPP, but it can be adapted). As for the column, are you sure it is 30mm ?

Being a vintage British design, I would have expected an imperial size of either 1 1/8 " (28mm) or 1 1/4" (32mm).
