Thank you Pete and stratmando for the compliments.
The first correct number I found was 42,5. The second correct number I found, the second time I was there, was indeed 96.
I prefer not to say the last number as a courtesy to the owner. Since I found it by brute forcing the unknown wheel (trying all the possible numbers) it doesn't add anything useful to the thread. And no, stratmando, it was not one you guessed.
Cheers
