Need help in dating my Edison Triumph (not a banner decal) the serial number is 44-396 I'm also not sure if this is a B model or a A/B model? How can one tell for sure? Thank you

Your serial number is too low to be a B model, but it fits within the known range for A models. The A/B models began around No.45,000 (45025 is the earliest known A/B model) and ended around 50,000 (50,636 is the earliest B model known). NOTE: there is some intermixing of numbers between the A models and the A/B models. This is probably true with the transition from A/B models to B models as well.

The so-called A/B model Triumphs have a model A mechanism in the cabinet we associate with a model B.

I was just today discussing with a friend my frustration in not yet developing a dating formula for the Spring Motor/Triumph Phonographs. Admittedly, I haven't delved into this for at least the past 6 months. Perhaps this winter I'll give it another go...

Sorry I can't be more specific.

These A, B, A/B model Triumphs confuse me also George

George,
Would you let me know the manufacturing date of my Triumph A, Serial No 35613?.
Thanks in advance.
Alistair.

Alistair,

As I wrote above, I have not yet developed a 100% reliable dating formula for the Spring Motor/Triumph. I have put in many hours of work on this, but for every combination of Triumph-derived machines to be included/left out, there has been a glitch. I have a couple of ideas to try...

The Gem, Standard, Home, and Concert were relatively easy. Not so the Triumph.

I'll certainly post something here on the TMF should I "crack the code."

Thanks George,
I look forward to seeing your post when you crack the code.
Regards,
Alistair.
