Welcome to Truck and Bus Forum,
bingo.
If you search you will find posts involving Flxible Clippers (from Dunnunda) - but I don't think that there is anything technical to help you.
Search on 'John Tgood' and 'Flxible'.

It looks good cosmetically - what about the mechanicals?
Do tell the story about how you discovered it and what persuaded you to restore it.
