[sdiy] blue copper-clad circuit boards?

[Theo]

Your right, I was off about Bungard.
Should have known I still got 2 square meters worth of Bungard PCB material
in stock.
However I do also have some blue PCB base material in house, apparently not
Bungard.
Don't know what brand it is though.
Just checked with a home brew blue PCB but there are no markings on it.
I doubt the material is FR4 cause the edges are smooth, not rough glass
fibers edges.
Thing is I bought the material some 15 years ago, and I don't remember where
from.

Elektuur (Elektor) also use(ed) blue PCB base material, again the material
is Blue not the soldermask.
The new MFB synth II has a front panel of blue PCB base material (the older
model uses BLACK pcb base material).
So the material is still out there, problem is where to get it...
