Does this stamped #1 look correct for Tonawanda

[bergy]

Looks good to me - I worked at the Tonawanda complex back in the day. Multiple vendors caused slight variations in charactors. The only way that I know of to be positive is to have access to known, real stamps that were just prior and just after this stamp. If the charactors are the same - you can be pretty sure that it's a legit stamp. Al Grenning has a huge data base, but he only certifies Corvette stamps. Jerry probably has a good data base for Camaros.
