Arnold is unussual becasue they seem to have made many checks for the Seaboard Airline Railway, and just for the Seaboard Airline Railway. I wish there were more examples in existence, but this is the way it goes!. The examples I have are thick and very nice designs. The lettering is excellent in quality.

I need information on this maker.

Arnold check

This "Local" designation check for  the Seaboard is fairly common.  This specific example has excellent patina.
