I can tell you a little of the L.C. Smith. From the picture and with not having the serial number, it looks to be a 3 pin lock. These were made until 1906. The Royal Steel barrels first came out in 1898 and at that time, were the cheapest of the 3 barrel types offered then. An F grade with Royal Steel barrels cost $20.00, Best English Stub Twist, $23.00 and good Damascus, $25.00.
This gun, if deemed shoot-able by a qualified gunsmith can still be used with low pressure, low velocity shells that are under 7500 psi and 1150 fps.
That is a nice thing you are doing by passing them down to the next generation, and hopefully passed again.
