Picked up this old Pabst neon sign today. The transformer is not mounted to the sign, it is a stand alone. Transformer has PABST embossed on the top. The person I bought it from said he thought the transformer may not be the original one that came with the sign, that he thinks his dad bought the transformer later. Sign works great and is in near mint condition. Can't seem to find another like it to get an idea of when it was made, what the value might be, etc. I have had a couple people say they think it is worth $500-600, does this sound right? I am thinking 40s or early 50s. Any help appreciated! Thanks! Scott
