old electrical bits for My project building a dim tester (Erith DA17)

Hi All

I was wondering if anyone has a few spare old 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 1M (if longer then this is ok)
Three pin UK Plug
Plastic Twin socket with back box
Plastic single socket with back box
(Need both for input and output)
Light bulb holder and old 100w bulb

I will appreciate it very much

Thanks so much all amazing community

Many Thanks
Kind Regards
