The first belt is the Model 1912/36 Pistol Belt. It retains the construction of the Model 1912 belt, but has the Model 1936 alloy closure. It still has the snap for the 1911 magazine pocket.

The second belt appears to be the Model 1956 Individual Equipment Belt.

If you are looking for a rig to match the time period of your Model 1911, both are too late.
