Not really collecting vintage blades but have amassed a pretty good selection of current & NOS blades, about 180 different blades. While getting those and buying some old razors I have received some vintage blades. More than happy to let you have them if you want, pm me your details. Can't remember off the top of my head but I think there are some Plaza, Ever Ready, Chade, Gillette Thin & 7 O'Clock.
If anyone else is interested, I have a lot of the Plaza & Ever Ready which I could PIF.
