The Canadian engineer's iron ring is intended to be a personal reminder, to spare 'neither time, nor steel, nor stone'. Its origins certainly stemmed from the double failure of the Quebec Bridge over the St Lawrence river.
Canadian Architects also originally wore the iron ring but later adopted a silver ring.
The 'Obligation' was indeed written by Rudyard Kipling, who was born in the same year as the sponsor, distinguished Canadian mining engineer, Professor HET Haultain.
My own ring was presented to me personally by Professor Haultain, in 1952 at Camp No 1 Toronto. Another example of the ring can be seen in Kipling's last residence at Bateman's, Burwash, Sussex.
As part of the Canadian scene, the ring hardly seems to be appropriate for either the UK or the USA historic backgrounds.
