Okay, I think we have the same variant! I wrote down the numbers from my last game. They were 13 12 24 34. The two nos. in bold are the disks that toggle back and forth 180 degrees when you spin the drums. In my method, we need to get those two disks in their correct position first.

So, you can start by getting disk 1 into its correct position with the notch at the top. (I've never taken the slightest notice of the letters!) If you can't do this by spinning the first drum, then spin the second drum so disk 1 is either in the correct position or has the notch at the bottom (when you can then then put it into the correct position by spinning the first drum again).

Once you have disk 1 with the notch at the top, follow the same method to get disk 4 into its correct position by spinning drums 3 and 4.

Let me know if this makes any sense so far (maybe taking a screen shot of the puzzle will help), and I'll try to continue the explanation later. I'm too tired to continue now, so I'm off to bed!
