This plate has us wondering...
...What aircraft was this for?!

We can see that it was an overhaul plate but don't know what aircraft this could have been from. The only one's we're thinking of are:
OS2U Kingfisher
SB2U Vindicator
VS-44A
Earlier Flying Boats?
Or could it be from a Corsair? Any thoughts? Suggestions? Questions? Comments? Concerns?
