Hey Danny, when I re-designed the Hallmark roller bridge in early 2000, I decided to take out the issues of the vintage Mosrite and Hallmark bridges and make it perform better. The first thing I did was to rid of the folded sheet metal bridge deck and make it out of a solid milled block of brass stock instead.
The next thing I wanted was better bridge saddles that served two purposes. First, the string radius should be perfect to Hallmark radius and the rollers should be uniform in height unlike vintage Mosrite rollers. So I decided to make the saddles control the radius rather than the rollers themselves. So I developed 3 different size roller housings rather than 3 different size slots in the rollers themselves, for better performance.
When I developed this bridge it went through several stages of re-design until I was happy with it. So you will see on our first Hallmarks the first version of the bridge, and the second and third run the second version, and fourth run the third version etc.
The company that is making our bridges for us saw an opportunity and wanted to offer our bridge to other vendors, so we came to an agreement for a lisc. for our design and some slight cosmetic changes were made so we retain the look of the classic Hallmark bridge. Other than that they are the same design performance wise.
