The Admiral uses a vertical shuttle which quilters claim is best for free motion quilting. This appears to be true as the thread has fewer turns to make when sewing. (A horizontal bobbin requires the thread to make a 90-degree bend when it exits the bobbin.)

To clean and oil the shuttle, a small finger knob in the upper-right corner is rotated releasing the hold-fast plate.

When inserting the bobbin, the finger must rest in the detent as shown.

This Admiral has an attractive faceplate. It is held in place by a single screw.

Threading is a bit awkward as the upper thread tension and take-up arm are situated on the rear of the machine. However, threading is similar to that of Signers poplar at the same time period.

Stitch length and forward/reverse are controlled by this lever. When an internal disk is secured with the screw, forward and reverse stitch length will be the same length.
