Oceak was Danny Murtagh's 3B coach with the Pirates, from 1958-1964 and again in 1970-1971. (He also coached for Cincinnati in 1965, and under Bill Virdon with the Pirates in 1972.) Several B&W images were posted upthread (post 175), but here's a color picture from the Topps archive:
Of course, like many a Topps picture, the color is hideously bad. But I've gotten semi-decent at digital image correction; here's my attempt, with a cut down to 180x270:

Still a touch florid for my tastes (it's a problem I tend to have with images of redheads), but hopefully acceptable.
Since there's a uniform number on the front, that means this picture is from 1962-1964 (Bucs added the front number in '62) or, just possibly, 1970 (they wore the old unis in spring training and at Forbes Field for the first three months, as I understand it, and then switched to the doubleknits when they moved into Three Rivers on July 16th).
I wonder how Oceak's name is pronounced: is it "o-SHAK" (like "ocean") or "o-SEEK" or "o-SEE-ak"? Does anybody remember?
ETA:
Here's another image of Oceak, apparently misfiled a little later in the file. I think I did the color a little better on this one:
