I found some debris on a Yak-1 crash site. Most of them are alu plates with rivets and bolts, but a few one is more interesting. I would like to identify them, but I could not find any good and detailed drawing or photo about the cockpit, airframe, or the engine. Sure, somebody of You may have more information about Yak fighters and may find the answers what are these and where were the original places of these parts in the plane.
Thank You very much for Your help in advance.
