I hope that's what they are actually called - it's what it said on the quote, and the chap who measured up referred to them as such (I could hardly keep a straight face).

What on earth possessed you to look, anyway?

I guess I'm just kinky for ironmongery. Or brassmongery. Or whatever they monger to make these things. I thought it was an interesting fastener and I wondered if it was just a UK thing so I went looking around.

[Dan] Wouldn't it be more accurate to say this is the only site that calls them [the name that must not be mentioned]? Not trolling, but all the other hits I got in Google called them something slightly different (but with the same initials). By the way, I loved your "Rear Window" bit. It provided a moment of cheer in an otherwise lousy Friday.

[SM] It's possible that it's local dialect.

[rab] Good point. I am a long way from where I was brought up and occasionally, when I'm not concentrating or when I'm tired, say something "regional" that has people looking at me weirdly. I told some Canadians that I would "put the snack on" a Yale lock so they could come and go without a key. No-one understood what I was talking about.
