So, I went out shopping today and something followed me home. Anyways, I am trying to figure out the year of manufacture, and the only way is by the date codes on the barrel. Assuming it is all original, the whole thing should be close together. Anyway, while looking at the date code on the barrel, it looks like it reads 0DR (zero, D, R) but am assuming it is ODR. The only thing is that the O/0 is not as in line as the D and R are. If it is OD, it is a July 1957 model, and if DR it is a September 1968 model. It has no prefix putting it from 1951 - 1968, so either of these letters together are in the range. Just looking for an opinion if it is OD, or DR from someone else. Thanks.
