I’m not an expert on the vintage ones as many here are, but I’m feeling that the bezel may be a later service bezel. Not that there is anything wrong with service parts, but that should be reflected in the price. We had a very nice one for sale here not long about for about 1/3 less if I recall.
And yes, Bakelite get brittle like glass over time- they don’t take an impact well. (My watchco is acrylic so slightly more impact resistant). I have watches with Bakelite bezels and they get light duty. Not looking to be a weekend warrior with a long NLA part that will kill half a watche’s value if I whack it into a door frame.
