Swift Sixteen's own brand polished cast brass steam dome for the Mamod, IP Jane and RWM Janet.

Will fit any loco with a 38mm or 1 1/2" boiler, but will fit from 35mm to 50mm with gentle compression in a bench vice over a steel former (protect the polished top!)

The one thing that these little engines always seem to be missing, are nicely shaped domes, or even a dome at all! Even if they have got a dome, they are often way too basic in shape. We have solved this problem with our cast brass dome that features a very nice boiler flare. 

This is a polished casting only with a large internal bore. It will fit any boiler of 38mm or 1 1/2". Because it is made with many engines in mind, we do not supply a means of fixing it to the water top up valve/safety valve, this is for the customer to make. If you need a hole drilling in the top for a water top-up tube or safety valve steam outlet, we do offer a drilling service for free, just ask after purchase. You would need to tell us your preferred diameter of this hole.
