Thank you all for your kind comments.
I found a second custom I made of a hydrant man in BA, photos attached. The equipment is the same design but I like the general look of the figure overall very much.
I spotted another hydrant cover in the village today which I will photograph and post as it is the same as my design. I did say that the letters F H were not accurate, but clearly they are. I suspect another senior moment and that when I made the custom (about 1997) I modelled the hydrant cover on t the village this one in and have since forgotten.
