Thanks Pharmer.
JoCo -- Thanks. I must have seen an earlier post of yours regarding the clean up method.
In my Vintage Toolbox post, I mentioned both locks being locked closed. After a trip to a locksmith, the barrel lock on the bottom chest was easy, now keyed. The top chest was more challenging. After grinding a couple notches in a blank, I told them I was a tinkerer and would proceed on my own. He looked in with a light with magnification and opined there were two spring-loaded prongs that needed to be pushed (my wording, not his) and gave me a couple blanks to play with. Attached is an image of the lock. I'm hoping someone has a key from their similar box and will post an image so I can get an idea of what it looks like. I've looked online and have not yet found anything.
The lock says: Eagle Lock Co., Terryville, Conn, 49Y39.
Thanks.
