I am looking at an Aqualung regulator set, but the seller does not know what model they are. It looks like legend 1st stage and a titan 2nd stage. Can anyone help identify them? Pics the seller sent are below.

The Titan LX and the Legend look to have the same retaining ring.

Yes, it might be Legend -- does it have cracking adjustment?

Either way the internals are mostly the same and parts kit are now the same.
 
Both the titan lx and base model legend 2nd stages are more or less identcal. Do the serial numbers match? Appears to be a non-ACD legend fist stage.
 
The first stage is a Legend Series (2002-2013)....the details on the environmental cap (dots around the hex fitting opening and the marks around the circumference) are different from the the Titan LX 1st stage which had a pair of holes in the top environmental cap for a pin spanner.

The design of the environmental cap on the 2012-2019 Legend and Legend LUX was different than the depicted 1st stage as well.

The holes in the 2nd stage diaphragm retaining ring are indicative of a pre-2009 Titan LX 2nd stage:

The only thing throwing me for a loop is the round piece in the center with the cross hairs, I don't see that in any of the diagrams for the Legend or Titan series 2nd stages...I have also referenced pictures of the diaphragm (part# 129150) and do not see that feature:
