I was taking apart a very well constructed Meltrope iv sound-box because the needle bar had become mis-aligned.
I have only ever dismantled one other Meltrope which was a model iii - Decca 'chrome' type.
I noticed that there was an easily removable metal collar in the Meltrope iv which perfectly fits around the inside of the front body and is meant to be put in place after the rubber gasket is installed - to press down and make a tighter seal.
The Decca version has a similar shapped area but does not have a ring to remove. It all just seems to be a 'fused' to the body area - which makes a less tight seal. Trying to 'stuff' the rubber gasket in there just doesn't work well.
So I wonder, is the removable ring in the Meltrope iv common-place with most Meltrope soundboxes ?
Thanks as always for any help you can give.

Re: Unusual Meltrope sound-box design ???
I think they all have this, but sometimes it gets “stuck” in place and is hard to remove. The soundbox body is made of potmetal, albeit a seeming better composition than some of the HMV backs. I presume some swelling occurs though which makes that ring stick in place quite tightly.
I’ve several of these Meltropes and they all have the detachable ring.

As for a Meltrope IV. Is there such a thing. I can't say I have ever come across an advertisement or a marked Meltrope IV. The last version I know of, is the Meltrope IIIa with detachable chucks. These were made of cheaper pot-metal and have often swollen unlike the better quality of the Meltrope III.

I don't think there is a IV, but the example on the right is from a Sylvaphone and is branded IV so I suppose technically as it's a Meltrope, and it has IV on it, it must be?!chunnybh wrote: ↑Mon Dec 18, 2023 10:48 pm.

The other two are both IIIs but of different design.

In my experience some Meltrope IIIs have that ring, some don't. It's conceivable that the ones I've encountered without may have had one originally - I feel that's unlikely, but can't be certain. I must have a dozen of them or so, all of which I've rebuilt, though none recently. Seeing what the last example sold for on the Bay of Fleas the other day, I should probably sell some of them!

Thank you so very much leels and chunny for your information. I am now far wiser and greatly appreciate your help.

Sylvaphone was the brand name for gramophones manufactured by or for the Co-Operative Wholesale Society.
Any customer placing a bulk order for soundboxes could have their own name engraved on the front mask, as here :

Re: Unusual Meltrope sound-box design ???
Never seen a Meltrope II with that logo, I have one that has nothing on it, so may have been a blank ready to be stamped with a specific manufacturers name.
Interesting how more keep coming out of the woodwork!
