So my girlfriend's father handed me a Type 38 Arisaka (very nice, chrome-lined barrel, looks like it was restocked during the war) and asked me to fix it. Apparently he handed to his friend (a self-proclaimed firearms "expert") for inspection and when he got it back the bolt was locked up. Can't flip it up, let alone cock it back. Not quite sure what the problem is, but I've narrowed it down to the pictures I'll show you all. Back of the bolt appears to somehow be stuck on the shelf of the bolt release lever. I really hope somebody knows how to fix this. And no worries, the chamber is empty.
