Here's a new low profile replacement bridge for your vintage, or newer archtop guitar. This will also function well for flattop models.

The base measures 5/8" wide X 6" long. The height is 7/8" tall and will raise up to 1 1/4" high. 

If you want a lower profile, the base ends and the bottom of the saddle can be sanded down to lower the height another 1/4". The compensating saddle does not have string slots cut into it, so you can use this for whatever string spacing you may need. Will work as well for other new or vintage archtops such as....Kay, Harmony, Old Kraftsman, Framus, Airline, Regal, Silvertone, Epiphone, Gibson, Gretsch, and many more!
