Hi Steven and welcome. Sometimes ID'ing the old ones is a real process. There were models with very slight differences in detail that gave them different names. I think yours is one of these "splitting hairs" examples. It does have the outward appearances of being a Crusader, but the engraving is slightly different, as well as face.
We have to find a matching case in ads and see if the case can be verified having the face your example sports. As seen in 1929 and 30 ads below. Engraving is a close match (on the sides of crystal, but not ends) to 1929 Templar, but not lug shape. 1930 Crusador matches lug "sweep", but not engraving pattern. Crystal opening and face on yours match neither.
My guess is the face was swapped in the past, but still unknown if this is true. Sometimes it can take a while to ID these beauties. We appear to be seeing something different and perhaps never previously indentified.
1929 Templar ad 1930 Crusador
I'm at unknown and still looking.
