The one you see in my videos was purchased in the late 80's and has been hard at work in the shop ever since. It still works fine, but is getting so beat up that I recently invested in a backup one off ebay, just in case. RPN makes so much sense that I don't understand why anyone would bother with algebraic calculators, or why they even exist.
I recently saw a NOS K&E slide rule on the Facebook Marketplace, but as tempting as it was, I just couldn't do it.
