Matchbox Yesterday Y-9 Fowler "Big Lion" Showman's Engine, first released in 1958.
This lovely example is in very near-mint condition, with a couple of light chips to the paint, and a moderate chip to the roof. 9/10. For the best idea see the pics.
The box is original, complete, and in near-mint condition, 8/10. Lightly creased and worn, and with a minor surface tear and small puncture hole to the back, see the pics.
From a good collection of vintage Dinky & Corgi etc...
