The baseboard is a very nice piece of wood which was advertised as a kitchen chopping board. Sanded, cleaned and varnished nicely. Something I have learnt: Don't use Ronseal interior varnish - it's water based and doesn't do the job required here - use the oil based exterior varnish.
The Chiltern Steam boiler is now clad with 1mm thick mahogany strips and now has three brass boiler bands.
The 10V and the S50 are of a similar scale, so live together nicely. There is also space on the board for a condenser which I plan to make shorty.
Next job is piping from the boiler to a steam manifold towards the front of the board. That has two steam cocks - one for the 10V and one for the S50 - and possibly a fitting to allow compressed air in.
