Murray & Briggs Body Differences

The great pic above shows the Briggs Manufacturing Company logo found on a small stamping in a 1931 slant windshield town sedan. Thanks to Scott Schmeiser for the use of his pic. This similar logo has been found on firewalls, brackets, and other body structural parts on other cars.

The following pics show a side by side comparison of some of the detail differences between the same part made by two different Model A Ford body suppliers, Murray and Briggs.

The part shown for illustration is a LH front door window channel retainer as used on the 1931 slant windshield fordor sedans, victoria, and A400.

Unlike earlier Murray and Briggs sedans, the slant window fordor bodies were produced by both suppliers and were virtually identical in construction and the parts interchangeable. The differences are in the subtle details, as illustrated in the example below.

There are two primary methods of distinguishing the between Murray and Briggs slant windshield fordor sedans. The first is the firewall body builder tag (which is often missing), and the second telltale difference is the use of machined D-nuts on the Briggs bodies versus the widespread use of sheet metal wrapped square cage D nuts on the Murray bodies.

Here is a comparison of the same part, Murray on top, Briggs on bottom. Murray used sheet metal wrapped square cage nuts which were formed to fit and crimp into the D shaped holes in the part.

The Briggs bodies used the conventional one-piece machined D-nuts as used elsewhere on the Model A, and as also used in the bodies produced by Ford.

Both machined and cage style D-nuts were formed to fit and crimp into the same sized D-shaped holes in the part.

This view shows the differences in the style of D nut used, as well as differences in the way the section shape of the part was formed. Murray on top, Briggs on bottom. Note the extra fold and spot welds on the Briggs part.

This is a close-up showing the raised reverse image Briggs Manufacturing Corporation logo stamped in the steel from the other side.

This pic shows the thread size 8-32 stamped on the outside of the square cage D-nuts as used by Murray Body Corp, as well as a close-up of the form of the Murray part section.
