Bio degradable?

[PeterBurgess]

Just doing some work on a cylinder head for a Triumph 2000 Roadster, 1948/49, like the car Bergerac drove.
The customer supplied some new exhaust valves, they came in a Tranco box and the valves were wrapped in a waxed paper, just reminded me of the little waxed bags of salt in crisps in the early 60s! The paper has started to break up, so we must have hit the bio degrade effect after about 60 years

I thought this was going to be a thread about mid 90s merc engine harnesses.

Ha! Maybe Rover early 80s wiring harnesses were made at the same place!

I think Bosch made them, using a soya based insulation. This was one of the better bits, some of it just turned to dust as you touched it.

The cars were even more biodegradable...I'm sure not many lasted the same length of time as those wrappers ! lol
