For the escapement change, made on several models, Waltham printed the following illustration and explanation in several versions of their material catalog, and the revised parts have different part numbers. One can see the shape of the pallet fork in most images. The earlier forks have noticeably square profiles around the pallet stones. This change in escapement is why one has to be careful to get the proper part when replacing escape wheels or pallet forks on these models -- you can't just swap parts between 1894 models (or 1892 models) without paying attention to this or you will have a mis-matched escapement.
Changes and improvements... it's always so disappointing when you find a part and it turns out wrong. And sometimes you just don't know what's exactly wrong - looks all right, but just won't work properly
