How to make old rubber enlarger cords pliable?

[BobMarvin11225]

I buy just some flex of the type and length I need and re-use the plug of the original item .
Buying an extension lead is more expensive from what I have found .

Anyhow , cut the plug end off an extension lead and your left with an ( shorter !) extension lead without a plug !
You'ld then have to spash out for a plug for a very short extension lead !

Extravagance !.....

There's probably a different price structure in the UK. In the US an extension cord is usually cheaper than two-conductor "zip" cord and a plug, however little sense that makes.
