Showing frames 1 - a GIF of an AutoCAD redraw that I made of the1912 joiner. The joiner plans were found on microfilm by Tom Scott, which he printed and scanned.
The microfilm clarity was poor and many small objects could not be differentiated with other close objects
The three red objects are  the anchor chain chutes. Must have made a heck of a racket when the anchors were dropped
