Q: Can you tell me the value of an old tin-opener? It is cast-iron, and the end is shaped like a bull's head. It looks quite old.

Mr J

A. This sounds as if it is one of the original-style openers dating back to about 1880, a time when tinned food -- especially beef -- was becoming more common. Many firms made such tin-openers, some given away free as promotional items. Value is £10-£15.
