Shem,
Yup, I have written up instructions, with a diagram. The wording is as follows:
Assembly
1. Drill out the lamp as appropriate. For old style-drill base and front to meet, for modern-just widen the back hole.
2. Old style-insert LED and glue in place. Modern-thread LED wires & glue flat in the hollow section
3. Handle carefully as the wiring connection is very delicate
4. Old style-bend and cut 0.3mm PB wire to shape and superglue as lamp handle
5. Paint the lamp white/black/red/silver using acrylic paint
6. For a red light lamp, use a pin to pick up the 2mm diameter red filter circle. Place gently on a dot of superglue
7. Connect the longer LED wire to the resistor and connected to the positive. See diagram above.
