My second restoration and its a Stallman's Trunk

For my second project I was able to find a Stallman's Theatrical trunk which is in really nice condition. The exterior covering has a number of rips on it and the lock does not have a key but solid all around. Not sure the year but have seen most listed like this as 1880-1910. does anyone know if there is a way to know if that time frame is correct or what year might be closer for it?
