Triumph serial numbers

[shopdoc]

Dad had 6 Triumphs. In trying to figure out the models, I came up with the following:

Triumph A 30888
Triumph B 51197
Triumph B 60179
Triumph B 67608
Triumph F 84647
Triumph G 86361

My logic went that A was obvious, anything else with an end gate had to be B. F included model on the plate, and the last plate didn't have a spot for the model, so I guessed G. How sound is my logic? Does it make sense that B would span from serial 51197 to 67608?

The serial number on my Triumph E is 88440.edisonplayer.

Model G Triumph would be the one that only has 4 minute speed. The speed change pulley is locked on that model.
The F and G model use the 2 spring Opera style motor.

I think the serial numbers you show are too low for either model, Are you sure the "F" isn't a bad stamped "E"
Most F and G models I've seen have numbers in high 89,000's to low 90,000's

Never say never and never say always with this stuff.

The serial number on my Triumph E is 88440.edisonplayer.

Thank you so much edisonplayer and Chuck. I think you solved my mystery!

If they are both E, do these undersides make sense?

[ChuckA]

Yes, they are both Triton motors.

All Triumphs from Model A through Model E and the earlier Spring Motor model used that motor.
