Sadler was a Lazair dealer for some time before designing and selling his Vampires. He also modified his personal Lazairs quite a bit, and I think he marketed some of his mods. IIRC, he offered a conversion kit to switch the Lazair over to tricycle gear. He wasn't the only person to do this. I personally think it's a terrible idea, but each to his own.
Ultraflight did not supply serial number plates or decals, at least up through 1984.
If the engines have truly never been run, they may be OK, but Ultraflight used to test run the Pioneers before shipping them out. It sounds like you may have them, so the carbs may likely need rebuilding. If you have Rotax 185's, the capacitors (so called condensors) in the ignition systems may very well be bad by now. If you get a week or no spark, they are probably the culprit.
