I'm no expert, but my one experience with purchasing a 20 gauge Pigeon Grade from the pre-salt era that had been "upgraded" by adding raised white and yellow gold pigeon inlays into where they were ordinarily engraved on the action suggests it doesn't enhance value. The inlays had been done at the time the gun was originally purchased new from Paul Jaeger's shop in Jenkintown, PA. At the same time, Jaeger's put an oil finish on the stock and opened the chokes to improved cylinder and modified, adding the stamps so that the chokes were properly marked. I paid about what a Grade I in similar condition would have brought. I'm not a collector and really love the gun, but I can state with some certainty that the work, though quite nice, did not enhance the price.
