I found an ad for Dec. 48. Could be older. Fuller's Gaming Index says opened to 58. Was on next block but next to the Stockmen's that is still there. Jackpot was nearby. CHips from there, arrowdie $5's are around.
Sorry can't help on Town House Reno. I have no info. if connection or not. I want the Reno chip now too! I kept about 100 Reno chips I liked but can always add to it. I have 4 albums for sale. Sparks too. Keeping Tahoe & every single other small town chip I have though.
