The guitar is a Supertone, built by Harmony. Here is the information: https://jakewildwood.blogspot.com/2010/11/c1938-supertone-by-harmony-oo-guitar.html

It does have a slight hump at at the top of the headstock. The number inside the body references a Harmony model #, but nothing like the Henry L Mason. 14 Fret Slotted Headstock, not a very common combination.

Here's what I got from Gruhn's: Henry L Mason Guitar Made in the 1930s for Coastal Music in California. They are similar to Kalamazoo Models. This one is approximately 15” wide and 11” wide at the top bout. It has a slotted headstock, the length of the guitar is approximately 19” and 3 ¾” deep. It has a 25” scale and a 14 fret neck. Inside the guitar, stamped between the neck block and the first rear brace are the numbers: 3578 157. There is no serial # to be found nor are there any other markings. Tuesday - November 12th 2019 Hello Winnie, My name is Joe Spann and I coordinate the appraisal activities for George Gruhn here at Gruhn Guitars in Nashville. We received your recent email regarding a Henry L. Mason acoustic guitar. Henry L. Mason was a music teacher associated with Coastal Music in California during the late 1930's. He purchased large quantities of student-grade guitars to sell to his students. These instruments were built by a number of different companies, including Gibson. But Winnie, unfortunately your guitar is not one of those built by Gibson. Instead, it appears to be from one of the many Chicago companies (e.g. Kay, Harmony, Lyon & Healy, etc.). Current market value would be approximately $200. Thanks for your question. Joe Spann - Gruhn Guitars 2120 8th Avenue S Nashville, TN 37204 (615) 256-2033 joe@gruhn.com

There were screws holding the bridge on. I re-glued it and used some decorative screws to fill the holes.

Sorry it took mer so long to get back here. Here's some pics

I have that same Model Henry l Mason, rescued fro a wall in Willcox, AZ. I reset the neck. It is not a Gibson but has what appears to be a Harmony Model # and a 35 preceding it. It is similar to, but not the same as the Harmony 157, having an 00 size body and a 14 fret neck.
