Not without removing the chassis from the cabinet and then examining the chassis and switch to determine whether (or not) it looks old and original.

All 1929 Philco lowboys had those holes, nothing to be concerned about. Why did they have them? Who knows. Well, some long-dead Philco designer knows...but dead men tell no tales.
