...here you find some pictures:

But I can send you some more if you like.
I'm sure it is a different casting compared to the DreiBuchstabenMann part.
Hans are you sure about this? I've never heard about this. I believe he used his "own" casting and also sold these to others.

Re: Piston 93.5 Wossner
There was a discussion about it some years ago, but I don't remember where. Ask Kuntzinger, maybe he knows more about it.

Re: Piston 93.5 Wossner
...nice photos, thanks!
The DreiBuchstabenMann-cylinders are very reliable, but the machining by 3BM is quite poor, the Pami configuration together with a CP or JE piston is much better.

...I posted some new pictures here:

In my opinion it must be a JPX...

Re: Piston 93.5 Wossner
In 2011 I bought a Mahle piston which was finished by Helmut Wahl to 93.5mm and prepared for 88mm stroke without the need of an additional cylinder gasket (2mm).
It has a complete weight of 476g incl. clips, rings and piston pin.
Cylinder is definitely RAHIER.
The price for the custom made piston was 318€ incl. taxes.
Kind regards, Theo
PS: I have a second Rahier kit which has done more than 100.000km up to now with first piston and rings, still needs only little amount of oil![smile :)](./images/smilies/smile.gif)

Re: Piston 93.5 Wossner
thank you for your experience.
Mr Rahier Gaston was a pilot.....
Mr Rayer Christian, a kit maker....
in terms of the longevity of the kit and its sobriety in oil is strongly due to the famous U-flex scraper segment of a special technology .... and unfortunately not found nowadays ...
but the cylinder is not a Rayer, far from it.
maybe a JPX but I have doubts if it is not a reported shirt....
namely mr Rayer is still selling 2 or 3 kits which will have a 94mm Wossner piston...
and shirts...

Re: Piston 93.5 Wossner
I'm only talking about the cylinder itself, whoever casted them ...NOTHING he does is reliable...
Cheers,

![wink :wink:](./images/smilies/zwinkern.gif)
... not the machining...

I've never heard that one of these cylinders cracked...

Re: Piston 93.5 Wossner
Hi,
I ve compare my proto 94mm by Wossner and your plan and a 89mm Wossner piston (8505)....
Your plan look exactly like the 8505. Expect the diameter of course....
And looking the two piston I easy find who one is lighter than the other....

![Bild](https://i71.servimg.com/u/f71/16/99/40/77/20230211.jpg)
So I ll made a mix....
A 8505 with a less curved dome (compression 9:1) and diameter 93.5....
Thanks for your expérience !
