In regard to Wes Maxwell's post,I used to attend the International Watch Fob show in the 70's and many times since, in fact I was Pres. 1999-2003,wife Sec/Treas. George Pritchard of Marietta, OH made many fobs,after him there were more making new and repros.
Reproductions are a problem in about all hobbies.
I have stayed with the older original fobs in my collecting, E-Bay is loaded with repros, but I still find some very good one's there.I have collected since 1967.
