old used electric items for My project building a dim tester (Erith DA17)

Hi All

I was wondering if anyone has a few spare used electrical bits, please. I thought I would ask here and help the environment and reuse bits. The bits are for My own project. I am building a dim tester.

I Don't mind if the bits are covered in paint or have been used and are old as long they are working and not cracked.

Below is the list of items
round three core electrical wire. Approx 1 meter (if longer then this is ok)
Plastic Twin socket with back box
Plastic single socket with back box
(Need both for input and output)
Three pin UK Plug
Light bulb holder and 100w bulb

I will appreciate it very much

Thanks so much all amazing community

Many Thanks
Kind Regards
