From the estate of author, fishing guru, and winner of the Buz Buszek award, Andre Puyans:

For sale here is an Edward Vom Hofe Model 423 salmon fly reel in excellent overall condition. This serial number M322 reel was made in 1920. Size 6/0 - 4 1/4" diameter. This reel carries the 1896 patent stamp on the oil cap. German silver safety bands and pair of roller bars. The reel's drag is smooth and strong throughout its range. The reel foot is full length and not filed. Includes a 6/0 marking as well as the model and serial number. No cracks exist in the hard rubber and no dings to the rims. A fine example and still a very capable reel to catch very large salmon or steelhead. The original leather case is a bit ragged and shows its age.
