I recently came across a brown colored Sissell 201 spool insulator. It's not as spectacular a color as the salmon orange one Michael Green posted back in 2021 but neat just the same. So far I've found a white, grey, brown Sissell 201's and a small 2" spool Sissell 211. This company is hard to locate info on. All I could find is a company that made concrete burial vaults and other construction products by Lloyd D. Sissell and brother located in California. I also have some lag screw wire holders made by them recessed embossed Sissell and ones with a slanted S. There is also a wire holder with a M in a diamond that's the same mold as these too. Plus they even made a radio one too. Anybody living out there know of this company I would greatly appreciate any info or would love to find a catalog. I wonder if there are any other colors of spools besides the ones I mentioned. I love the embossing on these too.
