I have just sent an email to Ian @ rbaker.co.uk, 0151 ~ Liverpool ~ (No flop with Klopp)
This is the query about some old coils I have discovered. Maybe you could let me know what you think they were used for.
The thin steel box is some 7″ x 3″ x 3.5″ and was sealed by soldering. I have had it for some 32 years and more and it was old then. It was amongst a lot of bits and bobs when I bought an old trawler.
I opened it yesterday by cutting of the lid, slightly damaging the internals with the sparks. Still the item was wrapped and is fine.
The contents are four coils, approx. 6.9″ x 2.9″ x 0.8″
Being sealed and a box of four I thought it may be military spares.
Here’s a link to some images of it. https://unveiled.info/solect/the-soldered-box
