I did. There is no mechanism that'd eject the disk.

I guess it could be in the lower, central part of the photo but the construction there doesn't see /any/ wear at all. Meaning it probably never had anything mounted on it. No moving parts that would have left at least some marks. And the same in all I have..

If you could check if the one that actually does eject the disk looks the same as mine, only with some extra springs and levers? Otherwise that would mean even one more another... But I hope it was only CR that made the difference.

Thanks for the link to the picture. It doesn't provide enough detail for what I need but the drive looks indeed like those used in later 1541s with lever. Those I should have somewhere so in case I don't find the "-II" I may check the levered version of 1541 to do my comparisons.
