Thanks for your follow-up post George. Yes, prototype may be the correct description. I can find no serial number on this reeded edge bronze or brass piece.

For those who are interested in viewing the 4 piece silver set, click on the link below to the Silver Striker's on-line catalog for the complete Bally's car set. I will submit this brass piece to the webmaster for inclusion. It may be a sleeper that is undervalued on ebay.
