3 1/2 inch gauge BR Class 7 4-6-2

A well advanced 3 1/2 inch gauge Britannia to LBSC's popular design; work to date is to a good standard throughout.

The silver soldered copper combustion chamber boiler has had a twice working pressure hydraulic test with new certification issued - it's nicely made with neatly flanged plates and good solder penetration.

The chassis is still slightly tight but rolls without tight spots. It already runs very well on air in either direction, with some running in it we suspect it will improve further still.

A good starting point to produce a fine example of a Britannia for little additional outlay other than time in the workshop, we'd be interested to see this one when finished.
