Vintage valve cover and breathers?

[ssl78]

Do these breather look to be vintage?

I believe 59-66 283's used those script style GM covers. The breathers look old but I do believe both the covers and breathers are reproduced today fwiw.

They still make these today, the design has been the same since 1960's
