Possibly a transition piece between the 46mm and the engraved metal 49mm.
Or is it possible that all the paint has just rubbed off?
In the late 50's to mid 60's plastic was all the rage, and was considered a premium material (
vis. the exchange between Mr. McGuire and Benjamin Braddock (Dustin Hoffman) in the movie,
The Graduate,):
Mr. McGuire: I want to say one word to you. Just one word.
Benjamin: Yes, sir.
Mr. McGuire: Are you listening?
Benjamin: Yes, I am.
Mr. McGuire: Plastics.
Benjamin: Just how do you mean that, sir?
I have a
1965 premium bamboo fly fishing rod. The end cap of the aluminum rod tube is made of green plastic. Today a similar end cap would be brass. For a long time I thought it was cheap until I called the maker to inquire about the rod history and casually asked whether the cap was original. The man who actually hand made the rod was still employed, so they put him on the phone - he told me for several years customers preferred the plastic caps.
You could infer the period as before the metal hoods came back into favor - probably around the time of the Super-Takumar introduction. That could possibly make a 49mm thread plastic hood a transition hood to the metal 49mm hoods (given that the 46mm Asahi Optical Co. engraved hood that fits my Auto-Tak 55/1.8 is plastic). The Super-Tak 50/1.4 w/ 49mm thread filter ring was introduced in 1965 - right around the emergence of plastic as a premium material.
Of course, if you have $471.45 just laying around, there are two excellent copies of van Oosten available at Amazon.
