Back to the 'Nail'
'Put it on the Nail' I believe referred to making a deal spitting on your hand, then shacking another deal makers hand and finally putting both 'deal makers' hands on the 'Nail' to seal the deal.
I suppose the point was it was a public declaration.
They could also swear on a bible but that assumes religion is paramount.
Get NCC, Arch, Ascent and our County Councillors to 'Put it on the Nail' and swear undying loyalty to our town in front of all "The Make a Noise Group'.
It may be our best option.
