Here are a few more from Mystic, probably the last ones I'll post, but only one of them is something you might actually expect to see there.

Here's a Model A, found in a warehouse-type area of the shipyard.



Here's the Sabino, a coal-fired steam ship from 1912. Note the dark smoke coming out the stack.



And here's a picture of the dead horse effigy used in the Dead Horse Ceremony. Sailors used to be advanced a month's wage when they signed on for duty. It was supposed to be used to purchase warm clothing, etc., but was usually spent on booze and hookers in port before setting sail, so they had to work the first month without pay, or "for a dead horse." After the month was up, the sailors made an effigy of a dead horse, hoisted it up a mast, and cut it loose into the sea while singing a shanty to the captain about how his horse is dead. You can read about it here. Scroll down almost to the bottom of the page; it's numbered 10.
