I used to examine the insides of city sewers via a crawler camera for a living. I might have something of a basis of reference. Is there a read-out that shows which way is up and how far down the barrel the camera is?

What I really want to know is the condition of the bore and how well it shoots. The barrel is a Stevens-Pope, a 22 rimfire from about 1904. If it was shot with corrosive primers and put away without cleaning, it is probably done for. Putting a liner in it will not do. If anyone has a suggestion, I would sure like to hear it.
