Narrative:

On my preflight walk around; I found a bolt in the left gear; gear pin slot. Bolt was approximately 1' long; and no aircraft markings noticeable. I re-checked the other gear pin areas to ensure that I hadn't missed another one. Upon returning to the cockpit I informed the captain who in turn passed my disbelief and findings to chief pilot on call.
