Here are two unusual soundboxes. The first is a Virtz based on the European Pianina Grand Concert. It's the only soundbox I have seen that allows for the adjustment of the angle of the stylus bar.
The next is a Meltrope 3 which looks like it is provisional patent approval. Note the front guard is the same shape as the profile on the patent papers. The back nut and rubber are a smaller diameter than the post patent models.

Great to see these.

Very interesting. Where do you find these unusual items?

Wonderful to see - particularly, the Meltrope. Many thanks, Chunny!

Those Meltrope pics are interesting.
I came across this Meltrope III a while back which has a different back design to the standard- and a different front. They’re not interchangeable.
Always wondered where it fit and if it could have been an early one or a trial type?

Very nice to see the chromed version. Looks great.
I suspect once Meltrope had the basic design , they would have tried out various materials to try and lighten the weight and also keep manufacturing costs down.

I have one exactly like leels 1@s, except that the mask is oxidised, not nickel (though the rim of the bezel is nickel). Like that one, mine has two indents in the mask to press on the stylus plate, rather than ball bearings. On mine, these are insulated with thin pieces of what look like leather, but they might not be original. The back is the same as both yours, but with a nickel compression collar, and suitable for a tone-arm of no more than ¾ inch OD. The indent system was also used on the Meltrope 4. Chunny's looks to have ball bearings, though with a different shape of housing from the normal No 3. Chunny, your compression ring looks to have unusual knurling, and also appears to be unplated brass. Could itbe a replacement?

I know Mr Wild "tuned" Meltrope IIs by adding leather pads to where the ball bearings meet the body... perhaps it's similar?
The bezel although looking plated is worn and the body is still potmetal which is annoying. That said the composition of the potmetal doesn't seem to be too bad or susceptible to expanding.

Could be, but I doubt it. What has happened here is that the ring must have ceased to the body and someone used an unprotected tool to force it and has also sheared the knurling away unevenly so now it looks different at different parts of the ring. The lighting in the pic also makes it look different.
The ring is smaller than usual and is the same as the Meltrope I.
And, yes! Wild did use leather to "tune" the Meltrope III
