I've added a half dozen Washington Jacks in the past couple years. These are all Schrades. From the Cut Co days there's a variety of 2201, 2202, 2203, and 2204s - there's even a 2209 in there that's a customized knife with ivory covers that Schrade never made but if they had their own numbering system would have called for that last digit '9'. The little Washington Jack front and center is also a Cut Co, a 2533. From the Walden era are examples of the 2OT and 3OT. There are lots of contract editions and SFOs in the group and plenty that have been rehabbed from a pile of broken bone and rust into some of the nicest knives I own.
