OK gentlemen, and I use the term loosely, about 10 years ago I approached a foundry here in London to cast up steel reproductions of the towing arms. To use the original arms as patterns would mean that the end product would be solid as they could not place a collapsible core inside to produce the cavity. This would produce an arm that weighed about 90 lbs. and cost approx. $200 each back then. To fabricate a split patterns to give you a hollow arm was about ( if memory serves me ) $2000 and then about $250 per arm to cast ( more labour ). I would think that you could almost double those costs today. If you had enough people interested, say 10 people, you would be forking out about $1500 for a set of arms. If there is any interest, I could approach A.G. Anderson Foundries again and get a more firm estimate.
