As stamcon wrote, there was no spring inside. Just a lot of soil!

What I found fascinating is that it was able to clean up into such nice condition--even though it's just a wire connector

As to the crimp connectors, I recall reading in one of Rex Cauldwell's books that the proper way to crimp is with a device that will apply equal pressure from all sides.

I have noticed that the orange store carries caps to cover the crimps on current-carrying conductors.

Winnie:

Are those crimp-on barrels also properly used for splicing together the bare ground wire in NM cable?

The DIY book I bought at the orange store shows that use. However they just show the brass "sleeve" crimped over a bundle of bare copper wires - no rubber sleeve or anything.

I use bare crimps on ground wires. It's not nescessary to insulate the crimp because the ground wire is typically bare anyway.

yep they were very popular over here in the UK..used in old house wiring.

well before my time though,must have thrown hundreds in the bin over the years.

I came across & still have (somewhere) some of those same Simplex - Holland wirenuts... I have a regular customer in Ocean Beach (San Diego) who owns a house built in 1927.. Those were used at pretty much most of the existing light fixture locations, along with the funky wax-coated cloth wire.
