74x brass

| Magnification | 74x | | | Aperture in plates | 0.92 mm | 
| Body plates | 40 mm x 18 mm | | | Pitch of main positioning screw | 0.88 mm | 
This microscope is #2 in van Zuylen and Bracegirdle. One of the three Haaxman microscopes, now in a private collection.
The eyeside view, toward the bottom of the body plates, shows some brighter brass and the outline of what looks like a larger L-bracket. Perhaps the threads wore down and Leeuwenhoek replaced the whole mount/screws/bracket focusing system as a piece.
