The number you gave is the serial number. Do you know which model it is? Which 38 cartridge is it, the 38 Colt, 38 Special, 38 S&W?
The Dragoon series were all 44 caliber and the highest serial number is XXXXX They were made in the 1840's and 1850's. All of the Pocket and Navy models were made in 36 caliber or smaller except for the 1865 which has a 5 shot cylinder. The New Line series were made in 38 caliber but all are 5 shot. The earliest 38 caliber with a 6 shot cylinder that I can find is the 1877 Lightning. It was available with 1 1/2", 2", 2 1/2", 3", 3 1/2", 4", 4 1/2", or 6" barrels without an ejector and 4 1/2", 5", 6", 7", or 7 1/2" barrels with an ejector. It is a double action with long cylinder fluting, and a blue finish with a case hardened frame and hammer. Nickel plating was also available. It was made from 1887 to 1919. The Blue Book values are:
Long, knurled cylinder pins will bring a 10%-15% premium, depending on condition.Also, an etched barrel will command a 10%-15% over a roll marked barrel, depending on condition.
Add 20% to 30% to the Blue Book values for retail prices.
I hope this helps you,
It would have to have been made after the patent date which is 1876. The only other that it could be is the 2nd Model New Line Series. The values are much less, about 75% less than the Lightning.
Can you attach a picture of the gun? It will be much easier if I can match it a picture from one of my books. Use the paperclip icon on the toolbar or you can try copying and pasting it to a reply.
Does it look like the following guns?
It is the 1877 Lightning that I quoted values on. I use the online version of the Blue Book which is updated weekly. The values given are current. There are a few listed on Rock Island Auctions which is the premier firearms auction house. The predicted sale prices range from $2500 to $5500 depending on the condition.
