Please help me identify this telephone:

I have some pictures, and that is all.  Never seen one of these before.
The first pic is an "after" pic. I did put in a new line cord, and add new cotton web on the handset cord.
The phone works well.

On first look, I would guess BTMC.

Local battery,  A.C. signaling...

Is that handset similar to a Western Electric F1 handset?


PS:
> the way the circuit diagram is drawn is typically BTMC, I added perspective work-up
> the model number 2872A is characteristic of the series I think I see a manufacturing label specifying Brussels. BTMC had factories in both Antwerp and Bruxelles.
>They had access to WECo patents for the F1 handset, which they did use in Europe.
