Yes - there are various changes to the model of 1903.
There are also some other variants of 32's. One is the regulation police.
Another is the K-32, which is a K-frame chambered in 32 long. Still another
is the 32/20's, which are a whole serial-number series unto themselves. They are
K-frames, chambered in 32 Winchester. And then there are a few early 32/20's
that were chambered in 32 long.
So - the answer to your question depends on which frame-size you are referring to.
