In fairness, you're right about there being a market so I don't know why they don't make them. Limited numbers I suppose.
I don't own an ISC replica shirt, but I do own a polo shirt and if that's anything to go by their sizes are quite big in my opinion though. Size L is similar to a Fred Perry XL and bigger than a Lacoste 5.
