You only have to look back a few years when
Glowworm had (still have) 6 pcbs which are
identical in operation and totally pin compatible, all
very different in design.

I assume these are all different sizes, and prices.

No, exactly the same size, even down to the positioning of the stand-off
holes

So 6 pcbs all the same size, doing the same thing with different opart Nos?
How odd. But I'm sure different prices.

So it is probably worth
using the cheapest of these boards,providing you can get a fixing for the
board.

Well you of all people (cough) should know that doing that would lay you
right open for installing the wrong pcb

But they are all the same according to you, so yiou can't fit the wrong one.
