When I first got mine I had a Daughter just older than yours appears.. She has a 7 year old now and I'm just getting round to putting the old Refined Bauxite gal back together.. Your neck has the same primer stuff mine had in it..
Nice score!!!!
My end-pin is a one piece unit similar to the ones that the early Kays had.. I did have a similar tailpiece on mine but it had the "E" Keyhole broken out.. (Someone had strung it with 4/4 strings and bent it and did some other damage)
Your bridge looks a lot taller than mine is, so I suspect Mine has some subtle damage I don't see, But I'm leaving it as is.. Aluminum is funny stuff. I've worked with it all during the machinist portion of my life and I"m still amazed at some properties it has. A couple of the guys I used to work on Bonneville cars with were trying to convince me to try to just anneal it and crank the neck back, I'm now glad I didn't because over the time I left it alone it returned to what I believed is close to its original shape..
Mine has a dusting of White latex house paint on it, over what appears to be a fairly complete original finish, But I have yet to figure out how to remove it without destroying the original..

I think I'm just going to get to playing mine..
Soon as my finger heals..
