I was at a garage sale this morning and saw what I thought was a Stanley 9 3/4, so I grabbed it and threw it in my bag along with a few other goodies. After I paid, I went out to the car to start giggling in private and noticed that the mouth adjuster wasn't what I normally see on a Stanley, so I looked at the iron and, sure enough, its a Union. So, is there anyone here that can tell me what model number Union equates to a Stanley 9 3/4? TIA!!
