You guys have got to stop this stuff!  I have been following this thread recalling my novice days.  I never did get a regen receiver to work to my satisfaction, but I built my novice transmitter and struggled with an NC-54 (or was it NC-53) receiver.  I did not work many stations until I obtained a BC-348J receiver.

Later, I went on to build my own version of the Lew McCoy HBR-16 which featured an Eddystone slide rule dial and used salvaged (and capacitor switched coupling for variable selectivity) 85 kHz IF transformers  salvaged from BC-453 receivers.  I added a Q-multiplier at 85 kHz and it had really good selectivity.  I dubbed it the HBR-18 because it used 18 tubes.  It is still in the attic storage, and I might resurrect it one day.

I usually get enough nostalgia walking around hamfests and looking at the boat anchors for sale - seeing stuff I either had long ago or those things I lusted for and could not afford back in the day when they were available.  Wisdom has always prevailed and I have resisted the urge to take one home.

These days, my K2, K3 and KX3 are more than I need, but your comments have gotten me thinking about restoring that HBR-18 and the NC-101X that I have in the attic - even though I know that my Elecraft rigs are far superior performance-wise, much lighter and easier to use than those boat anchors.
I may even try my hand at a regen again based on some of the stuff presented by George Dobbs at several past FDIM seminars.

Thanks for the memories.
