Help IDing This 3 Pc Enameled One Handle Boat Set

Hello everyone,

I am new to the forum, although been collecting cast iron for quite some time.

I recently came across an interesting set of 3 one handle pans. They are made in the form of boats. Could not find any info on them. Below are the pictures. Any help with id will be much appreciated.

Thanks!

Oh yeah, there is a mark, but very hard to make out:

Not sure it's ever been figured out.
