Serial Number help

[JWalker]

Just purchased a Zeiss Jena 5cm f2 Sonnar on ebay. Not in my hands yet. I have done some research, not sure of the vintage. Serial No. is 2270923. One list I looked at indicates 1913! I don't think it's THAT old. Appears to be usable on my Contax iia. Uncoated. Thanks

S/N 2270923 was produced in 1938.
