This looks like a straight line engine, not a rose engine. It uses a straight pattern bar shown clearly in the second photo, whereas a rose engine uses a circular rosette or cam which is makes a pattern when the engines headstock is rotated. Andrew.

Here's a modern rose engine that I manufacture. It's made out of aluminum and motorized.
