I think we have to take into account that IRM Mk2’s are produced on the back of the mass UK market product which helps make the Irish models viable. Also if I recall correctly IRM sell the vast majority of their products directly to help make them viable. Paddy Murphy sells all products through retailers as far as I’m aware, so all credit to him for maintaining a very competitive price.
I think Fran, Patrick and the team would be the first to admit that Accurascale tandem products help them justify the IRM products.
