G'day from Sydney.
Have you looked at EJ Winter ,Bolton Scale Models located in Bathurst NSW.
They do a half scale Rosebery type A hit and miss casting kit.
That is a great looking engine of Karl Benz.
And it looks like a Bengs Karl above it.

Hi Brian.
I made a " Bengs Modellbau Big Nick" and had trouble getting it to run, it would try to run at times at best.
This engine uses a rubber ball in the exhaust above the cylinder head. with trouble shooting I found the ball was bouncing on its seat and not sealing off reliably. I...
A simple truth. Do you want the horrible smell of diesel fuel in your workshop.
If I need to refuel a diesel car I make sure gloves are used. That oily crap lasts forever if you get it say on the steering wheel.
A petrol (gasolene) engine usually atomises the fuel in the intake air (fuel air fine mist) via the carburetor and the spark plug ignites this to run.
Kerosene needs to be vaporized for the spark to achieve similar fuel burn in the engine. Carburetor still supplies the fuel air mix and the...
Your picture shows a 180 deg crank which means BOTH pistons are at TDC at the same time.
180 deg firing is not possible.
Both cylinders firing at the same time is possible and would be fun to watch.
360 deg firing the more likely set up.
As Bluejets stated, your picture shows both intake valves open at the same time.
I have seen a horizontal opposed twin "2 stroke" outboard firing as a single but wait to see your crank photo.
Car alternators are designed to run at 600 Hz before the three phase A.C.is rectified to D.C. A car alternator can safely run at twice that speed it so it can generate 1200 Hz with no problems to the electrical system.
That's good to know, I was worried my setup might cause a horrendous...
I have now seen an actual full size engine that this model is scaled from.
I noticed the 'big end' lubricator is actually mounted on the 'con rod' forward of the bearing, not overhanging at the rear as per model plans.
I wish to reduce the risk of being "clobbered" at this area but finding it...
