Six of a kind

Wonder how many mpg the matchbox one does :-)

Thanks for the tip, PLG1958! I probably would have just thought there was a gap in my brain somewhere between the word "six" and the meaning of it! As in, six = 3!

In reply to your query, Mr. O, I'm back - tentatively.If my computer starts throwing more tantrums it may yet have to go in to the shop!

I had to take a double take to see the other three! Someone has quite a hobby there!
