This the left cabinet, taken about half way down. There are 15 glass shelves in each of my two cabinets. Top Shelves; Side Tabs, Lower Shelves; Spools. Yes, that cobalt blue Side Tab generally in the center is an embossed Spratt//Patent 1850. These cabinet photos highlight many of my personal favorite LRIs picked up in the past 39 years of collecting LRIs. Cabinets built by my brother, Alan.
