Your photo of the top of the bowl clearly shows that the pipe is in great condition. Is there a number, with a line under it (1950s) or not (1960s). The number is often found to the right of the other nomenclature (this is the date code)?
If the number has a line under it then it should be 1950 + the number, if there's no line under the number then 1960 + number.
