Trial-fitting the large double-radiused rear sheet.

Three-quarter view of the new bunker. The corner sheet is work in progress, not a new type of smoke deflector for working backwards!

Top of the bunker, showing the recess behind the lamp bracket (yet to be welded on). A lot more drilling is required on the large sheet.

An unusual view of some of the internal structure of the bunker, without baffles or coal plate, taken through a rivet hole!
