It looks like an L184 converted to an Aristo head. If the condenser head is not included, then the condensers would be superfluous (but valuable to someone looking for them !!). If you go to look at this, make sure both flat springs coiled up at the top are intact. Though with the much lighter Aristo head, it may work Ok if one spring is broken. Hey it is free, so if you wind up going to see it, just haul it (and any related items like lens boards, condensers, spare condenser head, bulb, power supply for the Aristo, etc) home and ask questions later
