Thank you. I have learned something today.

I always thought a 4th port would be for a manometer.

This was a failure production ca. 1960 - you may contact:

Under collection you will find your D 10 with double safety valve

I guess these are rare,

I'll take mine off the shelf in the morning I have it in the box and I'll send you as much documentation as I can I thought it was super special the first time I bought it too I still enjoy it but two safety valves is extra except on a real train where you might even want three

Thanks!  Does anyone know what the front port was originally supposed to have?  A pressure gauge?  A whistle?

This is correct.   small era of double safety valve oscilating cylinder exists.  add a second steam spout or feed pump

Hi,

Did Wilesco ever sell, perhaps for export, a D10-sized engine with twin safety valves toward the rear?  It has four ports on top, the steam feed and three threaded fittings.  it have been oscillating or slide valve? Also the two valves are set to different pressures.  Both springs slide smooth and snap right back but one has markedly greater tension than the other.  This one has an oscilating cylinder, not a slide valve. The underside of the base as metal stamped "Made In Germany", not West Germany.

I've got an odd duck here which is starting to look like someone built it from two or more broken engines, but the boiler and twin valves themselves look to be factory original to some model or other. 

Photos attached.  The front port has another spring valve which someone tried unsuccessfully to fit a third (!) safety valve in, but its clearly not factory so don't worry about that.
