Rob- I'd agree with Mike that it looks 1910s for the same reasons he described, but there are many exceptions/variations out there especially if this is some sort of hybrid/transtion glove. I looked at the spiral glove in the Smith book and it's hard to use that as a comparison,IMO. Who am I to question Gallacher(or Wong) but I'd question if that was really an 1890s glove without seeing an example in some catalog from that period.

Still continues to be a nice mystery...we need to dig up a catalog from 1890 - 1910 that shows some exampe of this type of glove. All I have are the old Spalding's online which don't show anything like this that is webless.
