Munising Wood Products

Estimated Chronology

The two block letter brand marks are the earliest, probably 1920's and early 1930's. I don't know if they were used simultaneously or one before the other. Apparently the earliest production in the teens was not branded as I have heard.

The next oldest is probably the straight script with the M with pointed tops. I have seen evidence of this being mid 1930's and likely to about 1940.

The newest marks are the arched ones and especially with the trademark R under it.

The straight script with rounded top M appears to run from roughly early 1940's (maybe late 1930's) to near the end of production in the mid and late 1950's.

There is a lot of missing info of this type. I have just made guesses from various bits of information and clues so don't take my opinions as strictly gospel!

Any info or comments anyone has regarding this would be welcome.
