Hue's mention of "useless crystals" reminds me that my stock of FT-243 and HC-6/U crystals on oddball frequencies is dwindling again.  Here at AF4K Crystals, I need them for rebuilding onto useful frequencies.
Does anyone have a stockpile of such vintage crystals?  They look like this 

FT-243 -   May have a bakelite or metal front cover.


HC-6/U           Can only use the ones with a soldered seam.  


Both have pins spaced about 1/2 inch (0.486") 

Let me know what you have and we can discuss how I can get them here for  "reuse" by current operators.  Reuse is the best form of recycling, right?
Thank you.
