They are not uncommon in the US, but they don't make that red anymore because of environmental reasons. Finding one in nice condition takes a bit of time, depending on where in the US you are located. That one looks like it is is pretty nice shape. I wouldn't use it as a beater, but I'd certainly use it.
Don't know how common or uncommon they are in the UK (which is really what matters for you in the end). Hopefully a UK member can pipe up about that.
