We took a trip to our local island park in Eaton Rapids, MI and found two cannon on display, a 1864 Parrott and a 100lb from 1862.
I hope these pics come out:
The Parrott:
For scale (With me and an XD 3inch for comparison)
The 100lb:
Introducing a 20 pounder to cannon at an early age...
I hope I haven't crippled someone's dial-up modem
