Identify The Thorn (T.C.E) LOPT

Have a rummage in the spares dept this afternoon and came across this B&W TV lopt a pattern part to Thorn spec. Looking to the Thorn lads John (jayceebee) & Jim (jcdaze) to help identify which chassis this is for. Without delving into countless manuals my gut is saying 1600 series. The LOPT looks new and is dated 3/6/1979.

Well, I'm out! - It's not even a jellypot!

I've been and found the circuit diagram covering the models below;
1690 12" models 3845,3848,6845,
1691 14" models 3840,3847,6840 ,
1694 12" models 3857,3858
Originally a different transformer was fitted depending on whether it was a 12" or 14" model. A common transformer was then made available and it's pt. no. was 06D3-048-003. The pinouts are the same as the one you've got.
Well now, could it be for Thorn 1615B (3852), as in the set that Mikey66 forwarded to me?
Ah, right! I didn't think it was that tiny, and looking at the photos from the 1615B, this LOPT looks deceptively the same (more conventional) shape as the outline printed on the PCB - The LOPT is out of sight on the component side.

Late in the day and I wasn’t 100% sure but I would have said 1690/1, the grommet on the EHT lead gives it away I think. Locates on the heatsink around the line stage.
John.
