WTB RCA MI-9449 Cones & Original Binding Posts for RCA Driver circa aprox. 1940~1950

Wanted to buy
Hey there everybody,

Curious who ended up with the stock of RCA MI-9449 cones that auctioned a few years back? They were selling in lots of 60 cones at 4.5k, I'm not that loaded so I just watched 'um sell... I need a pair - but if I can afford it would like to buy 4 or 5 pair and have a lifetime-ish supply. Idk what's a good offer, you tell me:

I'd also like to find a pair of this style of binding post, for restoring an RCA woofer which is missing them:

I would also like to identify any other manufacturers that used this piece of hardware, so if you recognize them & their cleanly-machined square slots, and would like to share the knowledge of the other possible sources (I.E. I'd like to part them out of a cheaper driver), I'd greatly appreciate that information... I could try to info-trade, I sourced a replacement basket from a cheaper driver as the donor...

Please excuse the cat hair visible in all three photos. The culprit:

Cat hair yes, but mouse poo, no. Everything in life is a balance of positives and negatives...
