Ok I have trying to search the site for help with identifying the marks on two razors I have. They both have an oval with an arrow inside of it. One has no other markings and has been heavily used with lots of hone wear. The other is marked with the following and has a large crack in the blade near the heel that might be able to grind out and reshape the blade.

J.S Holler & Co.

Not sure as to why I am not coming up with anything in my searches, most likely not using the proper search string.

Any help will be appreciated.
