Interesting that the B 8971 is much more expensive than the B7971, was this used in any commercial products ?
The B-7971 is an interesting study. It is listed at $15.85 in single quantities, which is still worse than the $5/each I paid for NOS surplus from Meshna in 1979. However, running that number through the inflation calculator for January 1970 to July 2023 and I get $128.18 (which is shocking to see how much our money has been devalued all these years).
When B-7971's appear on eBay, they tend to sell for around $175-$200 each. Not that big a markup over the original price when inflation is taken into account. Of course most of the tubes being sold are used but still, factoring in 53 years of time for something no longer made, the markup is not that big. I am guessing that Ultronics was paying the $9.50/each ($76.83 - 2023) price for the quantities they were working with.

Oh. It didn't attach.
My understanding is that the prices dropped a lot as time went on, here's another price catalog from 1970 that mentions most of the same tubes for much cheaper, with B-5750 types just $4@1000pcs - roughly $25/pc now.
Hi all,
Out of curiosity, I took a look at some old Burroughs nixie tube price lists, and took the prices (1-99 pcs) to an inflation calculator (1963->2023). Here are some highlights:
B-4991 (Miniature, $68.00) -> $677.10 B-7094 (Jumbo, $45.00) -> $448.08
B-4032 (Miniature, $33.00) -> $328.59 B-5971 (13 Segments, $16.75) -> $166.79 6844-A (Standard, $11.00) -> $109.53 B-9012 (Pixie, $5.00) -> $49.79
I know that these tubes were made pretty much exclusively for military/non-consumer applications, but it's still interesting to see just how expensive nixies were in reasonable quantities.
