Search the net, there should be some, San Antonio is a very large city. 50 or so years ago there was the Harkness pipe shop, but I believe it's long gone. And the last time I was there, about 20 years ago, there was a father and son team that owned at least 2 shops. One was along the river walk. If this is your first visit, I suggest you tour the river walk and see the Alamo which is right by it. Good luck.
