Our joust troupe has decided to go with a 15th century time frame. I ,being the difficult one, have decided to go Irish. I'm thinking chainmaile, coat of plates, gambeson and a great helm. Sound about right? Any help and or research material would be helpful.

Where is the group portrayal located (I mean where are you "pretending" to be when you partcipate in an "event")? I would think that would affect your armor choices more than your personal background. Or are you portraying a tournament situation where people come from all over? What do you mean by "Irish Knight" - do you really mean a "peer of the realm" kind of thing, or do you mean a gentleman man at arms? Your social position and financial situation do much to determine what you have...

To be honest, I don't know much about 15th century Ireland, I do belive that it it was poorer than the rest of Europe and relatively isolated, so armour there might have been more old fashioned, but probably not 2 centuries out of date.

Edit: I've just found this on the myArmoury website, unfortunately it's about 100 years too late:
