The "berry stain" was removed and then stained Early American. The bottom half of the bar is oak and the top is mahogany. I have learned some about Chas. Passow and Sons through the Chicago Billiards museum (great resource) and some other web sites. I was hopeful someone out there knew more about the company, any records that might exist, other photos of a similar bar, etc. My family purchased the bar and the building during the prohibition era so we can't find out any information about it, except it was listed as a warehouse when they purchased it.
