Illustrator EPS export

[kinetica]

Hello

I'm sorry to bug you again. I have been sent an RGB EPS file. I have been asked to make a modification (very trivial) and return the file in CMYK. The file is a logo for Press (I unfortunately cannot attach the file due to contractual reasons) and arrived with me as a 12.8 Kb EPS. When I save or export the file (even without any changes), whatever format I choose, whatever options I deselect, the file is still huge. The smallest I have been able to get the file is about 380 Kb! Here are all the header comments from the original RGB file:

%!PS-Adobe-3.0 EPSF-3.0
%%Creator: 0.44
%%Pages: 1
%%Orientation: Portrait
%%BoundingBox: 0 0 419 127
%%HiResBoundingBox: 0 -2.2380573e-007 418.27719 126.12479
%%EndComments
%%Page: 1 1

So I cannot tell what application created this lean file. The headers for the Legacy Illustrator CMYK EPS I export contain:

%!PS-Adobe-3.1 EPSF-3.0
%%Creator: Adobe Illustrator(R) 11

The logo contains no fonts. It is a simple line drawing as you can tell from the size of the file I received. These are the settings I used. Can I not get this file any smaller? I've never come across this before.
