Guardian Brand BM20

[baseball junkie]

I recently found an old 1st basemans mitt.It's a Guardian Brand Eddie Robinson Model.On the palm it says BM20.It also has written on it Pro Maker and Trapper Model.I looked up Mr.Robinson on MLB.com and found out he played for several teams from 1942 thru 1956.I am thinking about selling this glove and would like to know more about it and what it might be worth.It's for a right-handed thrower and since I'm a lefty I can't even try it out.It's in pretty good shape for something as old as it is.
