The Reach was on ebay: https://www.ebay.com/itm/A-J-Reach-pat-date-1908-high-quality-full-web-fielders-glove/202082471893?hash=item2f0d0dcfd5:g:l3gAAOSw6SlZ4-dC
For the others, I check Hunt Auctions, Lelands, Mears, Robert Edward Auctions, Goldin, Heritage, Shopgoodwill, Etsy, Kijiji, liveauctioneers.com, ebay Canada, England, Germany. Some of the small auction houses have some nice surprises. The nicest Goldsmith Hans Wagner glove came out of a Baggers auction and the George Burns KenWel came out of Huggins and Scott auction. There are a few others I can't remember. You have to check every month. Just type in "glove" or "mitt" in the search window of a particular auction. I once found a nice glove by simply typing "auction 19th century baseball glove" into the Google search window. 99% of the results were months and years old but there was one current one from a tiny auction house in Florida.
