I had a similar case a few years ago, it wasn't a Philco though. On that one it was a woven material and the protective coating was dirty and stained. Very carefully I tried various solvents in an inconspicious spot and found that I could blot off the coating to the fabric with alcohol. I did that, and got to a reasonable stage, and harvested a strip of the material from inside the case to mend a couple of worn and torn spots. Then I sprayed the thing with orange shellac, and it looked 100% better, although not 100% perfect.
