Interestingly both my Astra soundboxes weigh 204g.
That's the Astra 5 (No Meltrope Clamp) and the Astra 6 (with Meltrope Clamp).
My guess is, whoever built the Astra soundboxes also built the EMG soundboxes.

Hello Graham and all of you, I have weighed my two "OVERSTALL" SOUNDBOXES and have the following weights, of which I was rather surprised to see.
TWO SPRING OVERSTALL 187 GRAMS.
four spring pverstall 250GMS
Yes, I was rather surprised at the two weights. I always thought the 2 spring felt heavier! George Overstall did have his own design weight adjuster, and used to show folks who were interested, that he could bring the weight on the record to ONE GRAM!and play a Long Playing record with a fine bamboo needle.
I did read years ago that those who used tri-angular bamboo needles, should use a heavy soundbox, as the weight compacted the bamboo point into a hard ball. I must admit that I also prefer a heavier weight using fibre and bamboo needles, as I found when playing heavily recorded gramophone records using a weight adjuster, bringing the weight down to under four ounces, that on heavily modulated grooves, the needle would sometimes skip a groove or two, and the point would need resharpening. I know some of the EMG and Expert chaps use weight adjusters with great effect. I only really use one if I have to play a worn record that I know would break a point quickly
I am sending pictures of both soundbioxes

Many thanks Alastair for sight of these fascinating, well made and extremely rare Overstall soundboxes. I can quite see that use of a weight adjuster might be necessary with the four-spring which is 10% heavier than the large Expert four-spring. Personally, I find a weight adjuster a little cumbersome for everyday use and seem to get consistently good results from the large EMG two-spring.

I am sure you are right about the same manufacturer being responsible for all soundboxes in the EMG and Astra stables. As far as I know, Astras were made for the Gramophone Exchange but do we know what Numbers 1,2,3,4 look like ?

Referring to a previous post on the Astra 5. There is an ad here for the Astra 4 and refers to the Astra 2 being sold for half the price. I cannot remember seeing any info on the Astra 1, 2 & 3, but being pre-1924 they may well have been advertised in The Soundwave magazine.

A few pics of the Astra 4 on the net. I believe it was available in mica diaphragm and with a "Specially built - up Composite Silk diaphragm".

Interesting: why is the price shown as 42/-, when it could have been 2/2/-, or even 2Gn?

Good point. I believe people generally dealt in shillings(a bob)rather than pounds. Average wage in 1930 was £165 a year. So spending 2 pound 2 shillings on a soundbox was pretty extravagant.
