I've not heard of them before and can't find anything either, which is not a good sign. Are they US or Australian manufactured?
If the frame doesn't have an MSO don't touch it!!
Looks like the frame should be ADR compliant and meet the 550mm rule, and those fenders would be perfectly legal too. Nice looking roller actually, and that's coming from someone who doesn't like swing-arm bikes.
Be sure to make sure all that paperwork checks out though, without it you would be in for an engineering nightmare. Looking forward to hearing what you find out about it.
Probably a better choice in the end, and you've probably saved yourself a lot of money and legal nightmares.
Says me who's building a complete Chopper from a swapmeet frame find LOL
