Ron poses a very good question. Although, we may never know for sure whether Mr. Alley produced patches or not, it does not seem unlikely to me that he may have, even if they were experimental and not produced in great numbers. Who knows, perhaps while setting up the machines at Sistersville for the first time all patches came out until the adjustments were made to produce pure swirls. And while some of the marbles found there are most likely from other makers, I do not believe any one type was found in large numbers (which is not necessarily to say they aren't still there somewhere).
If I am not mistaken, the most common patches found at the site to date have been the blue patches on that base that looks like it could fluoresce but doesn't. And when I compare those to other Alleys, it's not too hard to imagine that Mr. Alley produced them. Of course, without examples in original packaging or iron clad provenance this is all just speculation on my part. Nonetheless, the marbles below share identical colors (or as close as one could reasonably expect given normal variation). These colors also respond to UV light in the same manner. So I have no reason to presume that Mr Alley did not make this type of patch, at least.
