One of my current builds is a Trumpeter liberty ship (converted to post war generic tramp freighter). I had one of the cargo hatches disappear onto my wood floor. Searched, searched, searched, couldn't find it.
Finally decided after a week to scratchbuild a replacement. Got it glued in place, painted, ect. Glanced down at the floor, THERE'S THE STUPID HATCH IN PLAIN SIGHT!!!!!!
