Harmony H52 from the 1950s (date mark is not visible).   Outfitted with an early Gibson P13 pickup. A spruce top laminate body guitar that sounds and plays amazingly well.  The guitar truly captures the P13 vintage sound. 
It shows its age and and has several lacquer and surface cracks that do not appear to be through cracks and do not flex.  The volume pot shaft has been bent, but it is fully functional.   We elected to leave the original pot given its working order.  
In  40 years I  am yet to see a truly clean version of this guitar. These guitars were loved and played hard, this guitar is no exception, but it still has many good years left.  I recommend seeing and playing this guitar in person.
