I believe that may have been me, Bob. 

I used an RAL-7 as my main station receiver for over 12 years. I preferred it for my CW use over every other receiver I accumulated and used over that period.

I finally retired it to secondary status after I bought a Heathkit SB-100.

Other receivers I thoroughly enjoyed using were an RBB/RBC pair, and a BC-779 I modified by incorporating a good product-detector.

I used the BC-779 primarily for RTTY.

I was amazed at the HUGE improvement in the BC-779 due to the PD.

I have a couple of RBCs now, and both an RAK and an RAL, but have no bench space for them yet. I would like to find an RBB.

I also have two RBAs. Still no bench space.

Same condition for my R-390A, my R-389, and my SP-600-JX1 darn it.

I have a "thing" for receivers, probably because my very first ones were so bad.

But I really loved the RAL.

In US shipboard receivers, the RAL was the only HF receiver to use regenerative circuit.

Someone probably has a better memory and can recall the names or callsigns, but I remember at least one stalwart of the boatanchor list(s) from years ago who used the RAL as a primary CW receiver and said he'd put it up against any other.   I always admired that!  Anyone who has played with even a simple 1-tube regen knows how sensitive they can be, and with the RAL-type construction,  TRF front-end gain and selectivity, plus the audio filter I never doubted those claims.    Once you look inside an RAL it's hard to think of anything that could be done make it more rugged or stable, at least from a mechanical standpoint.

The RBB is a favorite of mine ever since one showed up in my driveway after a hamfest.   A local guy evidently figured that since he couldn't talk me into hauling it home, I'd at least adopt it if it turned up like a stray.    Something about cranking that tuning knob...
