In addition to the R-23 (and R-23A) and the R-148 that Robert mentioned, the
only other 190 to 550 kc receivers that had loop connections are the very rare
CBY-46102 of the RAV system (push terminals), and the R-11A of the post-WWII
A.R.C. Type 12 system (BNC).  The R-11A would not make a good "Q5er" because
it lacks a BFO.

You can begin with list member Gordon White's November 1964 CQ Magazine
article at http://www.scr-274-n.info/css.pdf .  Gordon wrote a wonderful
series of surplus-related articles which were the only real reasons to buy
CQ, 45 years ago.

You may also find the information at http://en.wikipedia.org/wiki/ARC-5
to be of interest.

There are very many related web resourses to be found.

>I was just using the term 'BC-453' loosely as a kind of generic reference.

On a forum with people who collect and study this equipment, imprecise
terminolgy may lead to miscommunication.

For example, there are moderate differences between the ARA/ATA and the
SCR-274-N systems, significant differences between receiver components of
the ARA or SCR-274-N and receiver components of the AN/ARC-5, and *very*
significant differences between transmitter components of the ATA or
SCR-274-N and transmitter components of the AN/ARC-5.  One must often know
the specific model to be able to comment accurately on a particular issue
related to an ARA/ATA, SCR-274-N, or AN/ARC-5 component.
