No two grading systems are alike. Here is where your gun would fall in the NRA Antique Grading. Fine-plus or Excellent-minusHere are more photos if anyone cares to give their opinion on grade
My own grading system would call it 60-70% finish with high point finish loss and moderate to heavy patina on grip straps. Stocks with worn points on checkering and some compression. Bore, unknown.EXCELLENT: All original parts; over 80% original finish; sharp lettering, numerals, and design on metal and wood; unmarred wood; fine bore.
FINE: All original parts; over 30% original finish; sharp lettering, numerals, and design on metal and wood; minor marks in wood; good bore.
I would call it Good to Good-plus. It is not close to Fine-Excellent, IMO.
And after good pictures like you have provided, the market would settle a value all by itself.
