These guns go for anywhere from $800-$20,000 depending on the condition, matching serial #'s and traceable history. I have seen 1 new in the box 1878 colt shotgun with factory letter that went for $10,000, and another 90% metal and wood, had some handling marks, that had some history behind it that went for $14,000. Most average pieces go for around $1,500-$3,000 in fair condition considering that they are over 100 years old at this point. A good source of information on firearms pricing iswww.gunsamerica.com
The Model 1878 was offered in 10 and 12 gauge from 1878 through 1889.
The Colt 1878 frontier model with serial # 35369 was produced around 1896.

According to this proofhouse website http://proofhouse.com/colt/index.html the model 1878 was only made up to 1905 with the final serial number being 51210. I don't know how much your gun is worth but with a serial number 117187 it is not a model 1878
