The manufacturer, but, I doubt if there is one single reference you can go to.
yes
No published sn data
Under the barrel release lever on the top of the frame
it should be located at the back of your pager where the seriel numbers and the barcodes are. thats where i found mine
Potentially tens of thousands of dollars. Seek the services of a professional appraiser
The Winchester model 12 book by George Madis seriel number data lists your gun as a 1953 seriel numbers 1328172 to 1398814
No way to answer.
These were made from 1939-41. It is very hard to tell what the exact year is on these motors as they didn't really keep track of the seriel numbers.
Generally substract the first two numbers in the serial # (27) from 100 and that is the year it was made, thus 1973 should be right.
When it was made.
the serial # is Q121214
