I took one apart takes ages and not worth it. Once you remove the tape and takje off the coiled copper, underneath there is more tape would round, take this off and remove the copper underneath and there is more wound tape.... Didn't get much copper from it compared to it's original weight and would have been similar if not worse price had I not just taken it in as is. The reason why it would smash is because it's not cast iron. It seems to be a plastic covered steel sheet wound round like a big roll of sellotape would be.

Those are one of the easiest transformers to strip. You take a grinder and grind around the side then the copper and plastic just peals off. Takes about 2 mins.
