Hello all. Just got off the phone with a fellow who is selling the above model. He says that's all the numbers it has on it and he thinks it is a 1954 but wasn't really certain. I am looking for a 54 so was wondering if this model covered more than one year and if so how would I be able to tell for sure that it is a 54. I have no pictures but it is green which I think a 54 is. As always thanks for any help. Rick.
