This is the 435 Bedford TK Tipper. I got it at a local shop for $8.00. It was missing the box sides and tailgate but I managed to get a replacement set of them. They are made of lead though and quite soft. I got an extremely good color match on the paint. You can see what it looked like before below.

It was made between 1964 and 1966 and measures 121mm. Possible variations with box and yellow cab with a black roof were made up to 1971. Another variation may have red hubs.

Below is another one I picked up cheap in a collection of wrecks. I haven't decided just what to do with it, but will post pictures of it when I do.
