Bona Allen did a large department store business and mail orde at one time and their mark of a B on top of an A wasn't on it. Or, a retailer would get a better deal for minor mistakes and again the BA was missing. Now, some of the earlier BAs of this style had bare wood trees with a muslin type covering which often didn't last long. The wood was then exposed to heat, cold and humidity which caused it to crack sometimes along the bars, from front to back or part way. Those may have been the department store saddles. I've seen some with rawhide covered trees and definintely bearing the BA. Do check the tree. A good place to look is up under the jockey. I rode 5 hours in a BA similar to this one and was ready to find another horse and go again.
