    I should also say I ve never seen the original leather finish so I don t have anything to compare this with. But this S/N is 64381...1918 vicinity. --Ed--

        I don't know the name of the chemical or the process they used - as I recall such finishes were made in various ways - some had vibrations made to the painted object, some had chemicals added to effect the finish.  There were leather finish, hammertone, and other finishes that were on radio equipment - hammertone was a fascinating one - it appeared on some Hallicrafters radios - and other radios - it looked like the paint was hit - and very uniformly - with a tiny tiny hammer about the size of the head of a finish nail.  Fascinating to learn that it wasn't produced by some little hammer device.

        Those engineers - what won't they do to delight us!

          David,

          Chapter 2 of W. R. Smith's great book " HOW TO RESTORE TELEGRAPH KEYS"
          is all about Japanning a key base.

          The ingredients are 2 parts of boiled linseed oil, 5 parts turpentine,
          3 parts asphaltum powder and 3 parts of rosin.

          How to do it is much too long for this posting, his book is the best
          source for the info. WR devotes 12 pages to japanning a base.

            Hello...

            I've reading this thread with interest.

            The 1932-33 Lightning I have has this Leatherette or "Crystal" finish on it. I'll post a close up to the photo section.

            I've never seen or heard of an example of the "Japanned" base in a crinkle design. But then again, I'm fairly new with this stuff as I've only recently been "bitten by the bug"... ;)

            I have seen the finish you're showing on that bug in another medium...it is on 1962 Gibson B-25 guitar that I own. Before I received this instrument, it had been frozen and warmed too quickly a couple of times while on tour in the early 70's. More likely, many times. The previous owner had a bit of a "who cares" attitude towards his tools of the trade. The cracking on the guitar looks very much like what I call the "orange peel effect".

            Either way...from all I've managed to gleam across the internet and libraries...the "Japanned" finish seems to have come in two variations from the factory...gloss and semi-gloss type of finishes. But then again, we all know the internet is never wrong! :)

              Hi Don, Yes, WR Smith s book is very excellent about japanning - but he doesn t mention what went into the sauce to make it look like leather - many times it

                Hi Don,

                Yes, WR Smith's book is very excellent about japanning - but he doesn't mention what went into the sauce to make it look like leather - many times it was a chemical process, sometimes a physical process such as dabbing more paint irregularly.

                David, You re correct he does not say anything about that. I wonder if it would be Tung oil. That s the stuff for making the crackle finish. -- 73, Don, NN8B
