There are several model 20 items in a Lawrence pre W II catalog including holsters, cartridge boxes and even a leather sap. There are no model 8 items. In a post-war catalog there is a model 8 shoulder holster & a number of model 20 items.
A photo would be invaluable, one showing the makers mark if possible. Otherwise a description might be helpful. Lawrence used the pre-war “football “ makers mark on some items after the war so that mark isn’t always an accurate reflection of when the item was made.
