Wow, looks awesome! As someone who used to build recumbents as a hobby I can relate to the blood, sweat and sleepless nights spent planning things out and weighing the options. Might not hurt to check with the local PD and see if the bike’s been reported stolen, just to make sure.
The labor of love that’s gone into rejuvenating this frame is inspiring! It would have been a shame to see it go to waste.
