Okay, year and value:
I can at least get you started. There will be others with vastly more knowledge and interest in such minutia will be along directly.
For openers, the star is a factory service mark indicating the gun was returned for service of some sort. I'm told (only told) there was a time when pretty much any and all items returned for work were refinished as a matter of course. That practice led to our knee-jerk reaction to suppose any/all guns with a star were refinished. I'm inclined to believe it ain't so.
The date code mentioned above may very well help with the determination of a refinish because of another aspect of star lore, and that is the practice of an automatic refinish was put to a stop somewhere along the line by someone with a collector mindset. Jinks', the Historian for a loooooooong time, comes to mind as a likely suspect/hero for stopping the practice----a hero because a refinish diminishes the value---a little or a lot depending on who did it. Current opinion puts the reduction at 15-20% for a factory refinish, 50% for any other. So much for that!
My input for value is next to worthless because it's applicable to target guns, and they're worth some more than fixed sight guns such as yours simply because of supply and demand----target guns deemed to have been something around 10% of total production. So, my two examples, early and later, fetched the amounts shown during the liquidation of my collection over the three years ending about a year ago. Both were high condition, original finish examples.
#42094, shipped December 22, 1908, fetched $3300.
#114655, shipped August 21, 1923 went out at $1225.
The rather startling difference can only be attributed to earlier and later. The premium for target guns is very likely treated in the Standard Catalog, but I wouldn't even begin to know where to look.
The shipping dates are somewhat meaningless when it comes to completion dates because the guns were neither completed nor shipped in anywhere near serial number order, and completion dates are seldom known -----or so we're told. (My best example of that is two 3rd Model Single Shots----#'s 4807 and 4826. Both guns were completed in May/June of 1911 respectively------4826, a special order, was shipped two days after completion on June 21, and 4807 sat around for FOUR AND A HALF YEARS after completion on May 9.) Go figure!!
