Feadog mark I

Hello all
Just got back back from East duhram irish week, had a great. I never thought I would get tired of irish music, but by the end of the week i was. Back on the topic, Jon Daly, great fiddle player, came to the place i was staying and was waiting for frank claudy to come out so they could pratice for the concert there where going to play in. Jon asked me if i wanted to play a couple of tunes so i said yes. i told him i had to go get my whistle. He told me to wait and pulled out of his bag a whistle. i looked at it and it said Feadog except the label was square instead of round, the writting was fancier, and the mouthpiece was lime green. Is this a feadog mark I? Jon didnt know, he said someone had lent him it in a session and he forgot to give it back. i played it and i liked it better than the mark II and III. If what a descride is a mark I then does any one have one they would sell or give to me?
thank you

I know Bloomfield has one, bloom does what i described sound like a mark I?
