We need to see the teeth....If it has the blade stops in front and the Y shaped teeth, then it is either a 1901 or 1902....Here is a quote from
@spidey9 :
Start of quote "The Kampfe Bros. Star lather catchers are identified by their patent dates. Since the razors are covered with patents, this can be confusing, but the relevant date is the most recent one.
Early models used side guides with adjustable setscrews to position the blade and allow for its changing dimensions due to repeated honing. Later designs had spring-loaded side guides and blade stops for the same purpose.
The models with blade stops will readily accept modern spined blades. Wet shavers, being a creative bunch, have devised workarounds to allow for use of modern blades in the early models but it requires a shim of some sort.
If you're looking for a razor specifically for shaving with modern blades, it is best to stick with the models with blade stops.
The 1901 and 1902 models have blade stops. Since sellers rarely have the correct model and the blade stops can be difficult to see in photos, the tipoff is the Y shaped teeth on the comb. If it has those it also has blade stops and modern blades can easily be used.
The Kampfe Bros. were convinced of the superiority of the wedge style blade and still listed the 1902 in their catalog until the merger with American Safety Razor in 1919, although they did introduce a few spined blade models (the Star Cru-Steel razors).
Thus, while the later lather catchers will readily accept modern blades they were not designed to use them and tend to be quite aggressive when loaded with one." End of quote
