{Collins} Am Filter in my r/e 75S-3B

One and all:

I picked up the inrad AM filter and in
looking through the manual on my r/e S-3B
it says "receivers supplied with the -011
status have been modified in accordance
with paragraphs "a" and "b".
How does one figure out if my radio was
supplied with the "-011" status....???  It
would seem some models were modified to
just slip the filter into the "spare" slot
and away you go.
Other radios - (I suspect earlier models of
the S-3B.. maybe) , one had to do a little

My receiver is in the  #85XXX range r/e
