Is this a windup? - It certainly is!

This is part of the roof vent opening mechanism for the arboretum in Cambridge University Botanic Garden. The botanical garden is famous for many things but most notably because it houses a direct descendant of Sir Isaac Newton's (1643 - 1727) apple tree.

Yes that tree. with the gravity and all.

This industrial revolution era winding gear is my contribution for #MonochromeMonday hosted by @old-guy-photos. It's a fun photographic task and one that I try to do often with a little help from my friends. In this case my daughter Natalie supplied the raw photos and I edited them.

I hope you enjoyed these photos of things that were built to last? If you are interested in monochrome photography take a look at these posts below. It is an interesting genre.
