4 Light Railway Signal

This 5 1/2 inch high model shared no components with number 29 or number 33. The pale green base and black column were different castings with a black oval head containing the red, amber, amber and green lenses. The 4 1/2 volt battery was mounted in the base and light sequence was obtained by operating a 4-position lever on the right hand side of the base. There are two different versions of this model, the earliest version has 4 bulbs (one for each coloured light), the later type has just one bulb which swivels in front of each coloured lens in turn.
