Apologies for the mistaking title

Hi

I am learning  modeling ATSF in the early 1960s so i am using boxcars 40ft double doors of the Fe-26 type by Athearn 74901 [serial 6333] and 70161[serial 5914].Althought this boxcars have fine printing and test dates of the future like  1965 and 1969 they both seem to be built in the mid 1945 and have the same brown paint scheme with small circles that came out in 1959 and without aci tags

I also have other double door box cars like the Athearn 70875 MP [serial 80065] and 70879 RI [serial 161271] also built in  1947 but with fine printing on the sides in the early/mid 1950s

I would   please very much like to know if this boxcars types are infact prototopical to run with the above mentioned ATSF boxcars in the early 1960s in this format and paint scheme ?

thanks very much for your reply
