3 1/2 inch gauge "Britannia" - stock code 9948

A well-advanced 3 1/2 inch gauge "Britannia" to the LBSC design serialised in "Model Engineer" magazine.

Work to date is to a good standard and includes a largely complete chassis that runs well on air - there's some video of it here - along with a silver soldered combustion chamber boiler and painted tender.

The boiler is a finely made thing - fit of the plates, quality of flanging and economical use of solder all witness an experienced hand in its construction.

Model Engineers Laser stock a good range of profiled parts, including platework for the cab. Complete with drawings.
