Alan,
In reality all L.C. Smith guns were built to the same engineering standards, the higher grade guns had fantastic engraving, upgraded wood and internal Jeweled damascened side lock works. The field grade type guns, especially the pre 1913 00 guns were all hand fit and finished, you can not take one set of barrels from a Smith gun and put it on another L.C. Smith gun without having a master gun maker due major fit up rework. This was not just an advertising stunt made by Hunter Arms, it was actually the way the guns were really made. Your 00 grade gun was made with the same engineering, metals and high quality barrel articulation as the higher graded guns. If your Field grade L.C. Smith double gun was made today, the starting price would be above $5,000, using CNC machined parts, the final hand fit and finish would drive the gun up to about $7,000. This was one of the reasons Marlin discontinued building the L.C. Smith gun. They found that in reality the gun could not really be built on a production line set up, way too much detailed hand work needed to be done. Never sell your L.C. Smith 00 Grade double gun short, in reality it is a very high quality side lock double gun.
I was hoping you would post a few pictures of your gun, so I could see the English Walnut wood your gun was built with.
all the best,

All grades of L.C. Smith guns could be Special ordered by the purchaser, L.C. Smith built and supplied more Special Order guns than any other American gun manufacturer. There are many Special Order 00 & Field Grade guns with up graded wood, special engraving and internal jeweled damascened side lock work. If you understand what you are looking at, you can collect some very serious L.C. Smith double guns.
