Thank you, Richard. The chart in TPS was dated 1920 which by then was based on modern shell dimensions I suppose. I won't be at the SxS, unfortunately.

The extractor was stuck but not badly; a little oil and it freed up in a minute.

I'm going to decide what to do with it next....I might decide to part ways with it but chances are I'll just let it rest in my safe....it will be the most senior of all my Parkers...maybe I'll let it sit next to my 241XXX gun!

Happy to be of help.

Not a bad looking gun Greg. A lot of patina there, but how many of them that old aren't.
