Mr. James' excellent research has uncovered a mine of fascinating information about these two rival British companies and the people who helped make these huge horned gramophones.
E.M.G Handmade Gramophones Ltd was founded in 1923 by Ellis Michael Ginn. Helped by Henry Seymour, Percy Wilson, David Phillips & Balfour Davey, he did in fact produce the best acoustic gramophones on the market.
However, in 1930, Ellis Michael Ginn, lost control of his namesake company and Balfour Davey found himself in charge of E.M.G.
Ginn subsequently started up the rival "EXPERT" brand. Francis James takes the reader through the intrigue, politics and rivalry of the times, to make this a compelling read.

These rubber parts are made from 100% Natural Rubber. Custom made to exact original specs.
TYPE A: 28.5mm x 20mm x 13mm. Replacement for most EMG, Expert, Meltrope II soundboxes to fit a HMV/ Victor re-entrant tonearm (~20mm). Try an EMG, Expert, Meltrope II soundbox on your re-entrant. On some soundboxes an additional washer is required for better compression. I will include a fiber washer with the Type A.
TYPE B: 28.5mm x 17.8mm x 13mm. Replacement for most EMG, Expert, Meltrope II soundboxes to fit a normal tonearm (~18mm)
TYPE C: 26.5mm x 17.8mm x11.8mm. Replacement for Meltrope III soundboxes. Also fits snugly into the 5A/B soundboxes and fits on an EMG, Expert or HMV 4 tonearm. There is obviously no compression nut but with a bit of talcum powder it fits perfectly on the tonearm without the metal ring.
TYPE D: 23.5mm x 17.8mm x 10mm. Replacement for some early EMG and for the Meltrope I soundboxes.
TYPE E: 28mm x 17mm x 13mm. Replacement for ASTRA 5 soundbox and some EMG soundboxes
TYPE F: 23mm x 17mm x 10mm. Replacement for some early EMG and for the Meltrope I soundboxes. ALSO a replacement for a HMV4 soundbox , It fits over the cleaned metal ring and snuggly into the HMV 4 soundbox.
(Type E and Type F are odd sizes I have found on some rare EMG soundboxes, they also work on normal EMG soundboxes.
TYPE G: Replacement rubber for a Davey Rollright thorn needle sharpener.
TYPE H: Replacement rubber for Victor Orthophonic, HMV 5A , 5B No16. This part has the all-important outer lip which creates an airtight seal with the tonearm. Without this outer lip your reproducer will never sound its best. It is exactly the same as the original, even having the knurled profile to exactly match the inner metal ring. This item is only the rubber not the metal flange within the rubber. You will need to remove your old part and use the original metal ring. Enlarge image on left to view knurling profile on the inside of the rubber ring.
My personal method for removing the rubber from an HMV 5A or 5B soundbox
The biggest problem is unscrewing the two screws. The screw slot head often splits and then the only solution is drilling them out. I soak the back of the reproducer in WD40 overnight and that usually loosens the screws to easily remove them.
Then try and slowly twist the rubber off. If that does not work, place a small flathead screwdriver inside at a 45 degree angle and twist. Do this all around; this usually lifts it out a fraction at a time without damage.
If that does not work, I cut the top of the rubber clean off and drill tiny holes all around the remaining rubber, between the body and the metal ring. This will remove it.
With my replacement the original metal ring needs to be removed from the old rubber and fitted to the new rubber. The replacement rubber has a profiled inside to fit the metal flange. Talcum powder will help with installing the rubber back into the soundbox. Drill a small hole in the rubber through the screw-hole and replace the two screws. All this at your own risk of course.
