Today doing a crossword I have learnt that a Polish cavalryman with a sword was called an uhlan.
Basic general knowledge surely?
I found out that Angela Lansbury dad was the labour politician George Lansbury!
Thanks oldspice
http://en.wikipedia.org/wiki/Rivets
A rivet is a mechanical fastener consisting of a smooth cylindrical shaft with heads on either end, the second one formed in position. The heads are somewhat larger than the diameter of the hole into which the rivet has been inserted. Generally one head is factory formed. The other is formed by clinching metal after the rivet has been inserted.
