Thanks Gary. I am waiting for my supply to arrive, but did not realize it was for leather as well.
I was looking at some material designed to preserve old leather (suggested by riflepit), including one version with lamp black to restore the color. The products appear to be well researched and of excellent quality but, on the other hand, it would then no longer be "original". Would I be opening a can of worms if I asked opinions about color restoration for antique leather (in otherwise excellent condition)?
The leather restoration compound instructs application to both sides of the leather. That makes sense to me. Would the wax be appropriate for use on the inside of the leather as well?
How about the lamp black version for the outside, the clear for the inside and a final protective coating of Rennaissance Wax on the outside? Any input is welcomed. I am a comlete novice and don't want to ruin a good piece with incorrect treatment.
