Is this a Model A handle?

[Chucker]

This handle is stainless clad, handle part appears identical to coupe, tudor handle, the part that fits against the door is flat not curved like a coupe handle, the shaft is 1/2" longer that coupe handle, and no original model a key will go into the lock cylinder. It has a matching pair of keys(not briggs) and the handle and keys appear to be N.O.S. Also the lock cylinder is not removable.
