Hi all.
My first post is about a recently acquired Edison Disc Phonograph, model A100, s/n SM 13439. It is in working order and appears to be it quite good condition with an Oak cabinet. It came with plenty of needles both loud and soft and 21 discs. I got it from an Aunt & Uncle, it was previously my Grandparents. We live in an 1880s home, so it really fits in well.
The A100 has two 'pickups', not sure if that's the correct terminology, one on the right is the original, the second is mounted on the left hand side and appears to be a later addition as it mounts over the top of an original label, it has wiring going to a potentiometer, presumably a volume control. I'm wondering if anyone can shed any light on this aftermarket addition as I've not seen one similar on Google Images. I will post a pic in the next few days.
Most of the discs I have don't have a 'jacket', once again not sure of the correct terminology. I was wondering if it's possible to buy them anywhere?
Also, is there someone who can give an approximate valuation of the phonograph and individual discs. Bearing in mind, it is not for sale, purely for personal interest.
Cheers, Smokey.

I do believe these jackets are available on ebay. Titled sleeves for 78s.

Thanks Carl, I found 'em, about $5 each. Cheers.

I also found the aftermarket electric Tonearm and Soundbox fitted to this unit, BTH brand, it would have been fitted around 1930, the gramophone its'self was manufactured between 1915 & 1919.
