The numbering scheme suggests the P125 was one of Phosco's earlier SO/H lanterns, coming between the first, bulky gear-in-head lanterns (the P120 through P123) and their less bulky replacements (the P152 and P153).

As a non gear-in-head lantern, it was probably designed for aesthetic appeal, being far more streamline than its contemporaries. However it retains the classic Phosware design choices of vertical grooved refractor patterns on the end of the bowl, overhanging canopy over the bowl and Oddie key.

This example stood somewhere in the Northamptonshire area and was replaced by Darren in 2008.
