Dogfish, from what I can see in your pictures, you have a Fraser. Probably put together just preceeding the Great War. The action is a Mauser 1902, IIRC.
The trigger is Fraser's Patent Trigger he used in Mausers and Mannlichers.
It is very typical (for some unknown reason) for Fraser takedown magazine rifles to have mismatching wood. Maybe he could buy short wood cheaper. Scotsmen are a frugal lot, you know.....

C'mon man, this is the internet. We need more pitchers!
