Matchbox 43c; Pony Trailer

The Pony Trailer spanned the introduction of Superfast wheels, early ones have black plastic wheels then came Superfast in 1970. Regular wheels trailers are yellow with beige or green bases. The Superfast release was yellow or orange and later beige. All of them should have two horses in the back

The Pony Trailer (43c) was released in 1968 and was converted to Superfast in 1970 remaining in the core range until 1971 with some later releases in 1976 through to 1983. None of them brings much of a premium, except for the later twin packs which can get a hefty price.
