JayHello,
I ran a query for you on all Niles cards. I then narrowed down for the years where he would be portrayed in Boston uniform. I have no idea, and hope it is one of the following:
1908-09 Rose Company PC760 Harry Niles 52
1909 Boston Herald Supplements Harry Niles 9
1910 American Caramel Die Cuts E125 Harry Niles 29
Let me know if you find anything,
Jay Kaplan
