I now have three of them. Two are from 1910 and one from 1886 and they're so different I doubt there would be many interchangeable parts.
The 1886 model's cabinet won't fit any other machine, not even other 15s!
Yes the 15s can be very different. I have been meaning to make a new thread on that since I think I have decades of different 15s around and they did make changes.
