> raw leather and leatherwork tools
You expect retail outlets for that? 30 years ago when I was making my own shoes in London and wanted to buy hide I had to trail around grimy industrial areas to visit a wholesale warehouse and persuade them to do retail for a moment. (I bought my tools from other hobbyists.)
This. People forget how much more stuff was niche or industrial/b2b only before ecommerce came along.
Industrial businesses were less rigid about avoiding retail sales than today but it was still way more hassle and generally "the dark ages" comparatively.
