The photos were the right way up but if you click on them they do right themselves.
Interestingly, the claims that each of the metal sides of the horn are a different shape and composition, not to mention clamped differently, is all true. It's a simple but very effective and well thought out design, clearly rivalling the Victor Orthophonic / HMV Re-entrant one. The sound emitted from this relatively small horn is astonishingly clear, bright and musical, with excellent bass, and lacks that metallic edginess some similar horns have.
Now, do I refit the non-original grille it came with or find an original MP22 grille to fit to it?

As I said when I started this thread back in 2013, Micro-Perophone was one of just a few smaller British manufacturers to produce machines of innovative design. It is unlikely that they could have afforded to tool up for anything as elaborate as the Orthophonic/Re-Entrant horn, so it was a matter of necessity being the mother of invention.
It was Alastair's MP22, which you now own, which inspired my admiration for these fine machines. I rather like it's Art Deco grille fret, even if it is not the original. I would refit it until such time as an original becomes available, as you may be in for a long wait.

No idea what a free edge suspension is
Picking up on this tiny detail (apologies if it's been commented on and I've missed it) - I seem to remember in the EMG book amidst the Seymour/Magnaphone era there's a reference to something that may be relevant or similar, along the lines of independence/non-attachment of the rim of the horn and the cabinet.

Yes, I know, but he's honestly asking way too much for it! Or put another way, would anyone like to buy a Garrard 11A motor (not currently working) with spare spring? There's nowt left salvageable after that.
