>>>>>"Wow guys that is really interesting - so do we think the dispatch rider's helmet offered for sale is a good one then? Eagle OK?"<<<<<<
It is always hard to say on these things without examining the piece in person. The eagle is not of the "standard" stenciled design, but that does not disqualify it, as I have more helmets with non-standard stencils than I do with the most commonly recognized design. I have seen a wide variety in the stenciled eagle designs, and many of those examples are "close" in their design and appearance to the most commonly recognized design, as the one on the EBay helmet is. So I would not dismiss this piece based on the fact that the eagle design is not of the type that everyone is most familiar with.
If I were buying helmets instead of thinning out my collection as I have been doing lately, I would probably give this helmet a serious look.
