Thanks for finding that information.
I'll have to get a copy of the SABR pictorial or that auction catalog and view it. I assume the "71" is for 1871.
I agree that the sock-shaped pin Wright is wearing appears to be the one in the 1872 Warren cdv.
It would still be neat to see the other 5 Boston championship pins from the 1870s. If anyone has seen them pictured anywhere please let me know.
Thanks.
