Wall bracket for LPL 7452?

I've just bought a used wall bracket for the above enlarger and to be honest I haven't got a clue how its supposed to be fixed to the wall?
I haven't any instructions and I cant find anything online so if anyone could post a picture of how theirs is fitted or explain how its done I'd appreciate it.

The larger bracket attaches to the wall, and the base of the enlarger is bolted to it instead of the baseboard.

The smaller L-shaped bracket attaches to the wall, also, and the top of the enlarger bolts to this piece. There is a slot in this piece that allows you to align the enlarger column to plumb.

Hope this helps. It's really pretty simple.
