I recently came across a Ruana 39C 'M' knife that was salvaged from a house fire. As shown in the attached photos the knife is in fair condition. The worst part is the handle which is really bad on one side.

The knife is 14-5/8" overall and the blade lenght is 9-1/4"

Can anyone tell me anything about the age of the knife, the number that were made and an estimated value? Would it be worth the cost to have it refurbished by Ruana?

Thanks
