Help with Professional Model MacGregor Basebabll Glove

[SSB15]

How can you tell if you have a professional model MacGregor glove from the early 1970's? What do you look for? Is the player's name bruned into the glove like you see in the Rawlings' store models?

Does anyone know where to look for a guide on gloves used by major league players versus store models.

Thanks

Scott
