[TR] Stag front seat workings???

[THOMAS FANSHER]

Anyone have a uncovered driver's seat frame?
I need to know how the tilt mechanism works. It's worked by the large chromed
lever to the door side of the driver's seat. Mine does not regulate the seat
back. The seat is in a not too comfortable rearward recline. I took the seat
out and tried to get a look but without removing the cover  and foam I'm at a
loss. It would help if someone already had one in that state.
Thanks in advance for any help
