Is this the wrong way round then. The glass was in the bottom (the last thing in the light path) when I bought the enlarger. Is this the wrong way round then?
That's the best way around, dust is less of a problem. A mask is a bit fiddly to make unless you have metal working skills, I made 2 35mm masks in mid 70's but I couldn't make a 120 version. Mine must have come with an enlarger.

Try Nova in Warwick, they may have something.
