[Elecraft] K3: Older Firmware File Versions Still Maintained Anywhere?

[David and Dianne on Comcast]

Hi Everyone,

Wondering if older versions of K3 firmware including beta's are 
available for downloading anywhere on the internet.

I'm specifically looking for versions back to 3.10.

I apparently deleted my own versions of these files somewhere along the way.

Thanks and 73 de N1LQ-Dave
