Oliver Name Cast on Manifold

[PeteAllen]

Can someone tell me what year (and month too if possible) that Oliver started having the Oliver name cast in the manifold?  Trying to help a friend narrow down the year of his HG.  It's painted green (1945 or newer?) with the IXK engine (no later than 1949?) and has a manifold without the Oliver name cast in it.

Thanks,

Hi;
My oc 3 had that manifold on it also. I belive that may be a 1953. I'm not sure of the year because it has no serial tag on anymore. but I found dates embossed in various castings and the carburetor has 1053 and the model #tsx 403 on it. I'm guessing it means Oct. of 1953.  it had the ixb motor in it.
