@WildEyedBoyFromFreecloud @nixCraft This is just the one segment i've preserved all these years later. The original full banger in my old shop was about 30' in total. The support legs had an upper & lower sleeved supports slightly offset. Somewhere think I still have some pics. Main thing is that it spares you that memory hole-laden labor of Sisyphus going through milk crates full of the superficially nearly identical looking bastards. You just run down the line & viola! Bobs your uncle. Done.
