Probably reprinted a lot
I did a quick Google after I posted this and I saw a red edition printed quite a bit later than mine (in the twenties, I think). Mine's definitely green and the binding is original.

I remember the x-ray tube and the fireworks. Incredible stuff; nearly everything in that book would get today's Handy Boy a control order in record time. Personally I enjoyed the electrical stuff; the best thing I made was a morse code transmitter from meccano and D-cells (range: six feet; frequency: all of them.)

Nice that others have seen it too; obviously it was a popular book for a number of years.
