It could be almost any USS SWB bent, but a quick scan of 
 https://www.google.com/search?tbm=isch&amp;q=USS+recumbent+SWB&amp;oq=USS+recumbent+SWB

suggests it may be something like


Haluzak Horizon    from https://bicycleman.com/brands-we-dont-stock/haluzak-recumbents/  but I note the stem is different.
HP Velotechnic Street Machine    from https://www.hpvelotechnik.com/produkte/sm/gt/pressespiegel/recumbentcyclist_070804_e.html
