stupid question 5904 alloy or ss?

[boatboy]

Is the lower ss or alloy? I think ss just a double check
Thanks Hank

The 5904 lower is alloy, upper slide carbon steel......5906 would be the all-stainless model

5904 has a blued allow frame. 5903 has a Satin Silver alloy frame. There was a 5905 blued steel frame version, but very limited production.
