Well found. Yes - I got mine from Mark Hennesy. It was in a cupboard at the BBC research department
where he worked, and he saved it from getting thrown out into a skip.

Thanks for remembering where the pics were stored! I used a pot core former, which was too high.
So
I cut a cheek off, shortened the tube and stuck the cheek back on (superglue). I used a cheap
manual
winding machine from eBay, and used Ulf's wind and retrace method to limit voltage from layer to
layer. Once finished I wax potted in an a mix of beeswax and candle wax (percentage - can't
remember.
Googled it), until bubbles stopped coming out, then gave it maybe another half hour to soak. Then
let
it drip.
It has worked perfectly ever since. The 576 was free, so time and not much money to get it working
again was a bonus.
The multiple tags on the bobbin were a boon - because the 0.1mm wire breaks a few times during
winding, you just terminate it on a pin and continue winding.
