Check the guitar!

When I was a kid, there was a "We Buy/Sell Anything" joint in our town.  I bought my first mandolin, a Martin bowl back, there for $20.
Once my brother Bob and I went in and saw a metal guitar with what looked like an old Studebaker hub cap on the front.  He wanted $45.  We laughed and said, "Who would ever want a metal guitar, especially for $45?"  It was probably an old National worth many times that amount, even back in the early sixties.
My only reso instrument is a ukulele, but my friend Ted has 3 of them, 2 Nationals and a Dobro.  Here's a ten year old photo taken the first time my reso met Ted's.  They played together many times in the Maple Leaf Champions jug band.
