Is it true that all 172cc sports engines had steel pistons?
Because my engine has an aluminium piston. Furthermore both of my engines has conrods which are marked with "VIII C"
Is this ok, or a part mix?

Many thank's for the answers!
This forum is really great!
My engine has a brass Bing carburettor, so that would fit to an pre 1926 engine. But as you say, it is also very plausible that someone changed the carburettor in the last 90 years.
Thank's to all!

Thank's for the answers.
My engine number is T 143* (the last one is *, because i don't want to post my correct engine number on the internet).

This engine belongs to a motorcycle from the almost unknown austrian brand D.S.H. This motorcycle was produced from 1924 to 1928 without any changes so it is impossible to find out the correct date of production (there is also no frame number on the frame). My last hope was the engine number.

Is it possible do find out when a Villiers engine (in this case my 172cc sports) was produced?
Maybe with the engine number?
As far as I know the 172cc sports engine was built from 1924 to 1932 (or so). So it would be very interesting for me to know the dathe year of production.
Many thank's in Advance

At first thank you very much for your answer!
That's very interesting and helpful for me.
Unfortunately the crankcase of the other sports engine was welded on exact this area, where normally the letter and engine number is stamped in, so it is impossible to identify the letter and number.

Dear Forum members,
at first I have to introduce myself:
My name is Ralf and I am from Austria.
Many thank`s to the admins for adding me to this forum!
Now to my question:
I have 2 Villiers 172cc sports engines. The crankcase from one of these 2 engines is stamped with the letter "T", which as I found out means that this is the sports engine for petroil lubrication. But on this "T"-crankcase are also the lubrication holes for the main bearings. The cylinder also has the oil connection port between the two exhaust ports.
Are the lubrication holes in the crankcase and the oil connection port on the cylinder correct for the "T"-type sports engine?
If yes, what are the differences to the "TL"-type sports engine with AutoLube-system?
Where is on the"TL"-type sports engine the connection port for the crankcase-pressure tube located, which is necessary for the Autolube-system?
Sorry for my midding english, I hope my text is understandable.

Many thank`s in Advance!
kind Regards
