This is the second portable set Pye released called the "Jewel Case". It may have been variously advertised as "P114BQ", "PE 114BQ" or "Jewel Case". The first "Jewel Case" is the Pye P131MBQ was marketed as the  "Jewel Case" and called "Jewel Case" on Pye Service sheet (early 1955 ior maybe late 1954). It's a larger cabinet (styled similarly) using a chassis with integral mains power supply, "tag strips" and "Point to Point" wiring. This model (P114BQ) is one of Pye's first PCB based sets. The Pye P131MBQ also has the chrome steel panel, but otherwise is different with dial cord and linear scale. The Chromed steel panel on the Mains/Battery  also serves as a "head sink" for the LT supply HT dropper resistor.

Some thoughts

Is the PE 114BQ really a different model or was that just an advertising leaflet for the P114BQ?

Example the Pye P131MBQ was marketed as the  "Jewel Case" and the Pye Invicta branded "Invicta 26" was variously marketed by Pye as Vicki and "Vicki 26"

The Invicta 28 from Pye is identical chassis to P114BQ as is the PAM712 (PAM716 also has mains). The Invicta 29 is also same chassis, not the older Pye P131MBQ "Jewel Case" (MB = Mains & Battery) but like one of the PAM (Pamphonic simply a PAM label for Pye by 1955)  PAM716? has the mains as a separate Chassis and a three way switch on same cabinet.

The battery only Invicta 28 and battery only PAM712 only  differ to P114BQ in case and year of manufacture. The Mains versions unlike Pye P131MBQ (Mains /Battery Jewel case, no PCB, vs "Jewel Case" P114BQ) are just the  battery only models with an extra Mains subchassis and extra switch on same case and front panel.

(The Pye  PAM710 was unrelated, being the first UK transistor set)

Pye strangely didn't put model plates on most Battery Portables. Vidor and Ever Ready at least added the Model name to battery guide label though some Ever Ready do have the Model name outside or even on the front. The letter "E" often means "Export" or Eire (Ireland). Pye did make sets in Ireland (as did Philips and Murphy in 1940s and 1950s). But the UK Pye 39 J/H (no Magic Eye) and Pye 39 JH/E (Magic Eye) differ on the scales, as the Pye 39 JH/E has "Dundrum" and "Ireland" on the scale. Of course "E" may be for magic eye and there may be a UK version of 39 JH/E!  In any case no distingushing difference is known for "PE 114BQ" and "P114BQ". They can only be indentified at all by appearance, lacking a Model name even on PCB or battery instructions.

Even the "Maker" name is understated

  • Pye Models: Small round Pye badge
  • Pye Invicta Models: Prancing pony on small round badge
  • Pye Pamphonic Models: Small badge with PAM or larger badge with Pamphonic

Just for completeness, the Pye P31MBQ (Mains+ Battery) and Pye P31BQ (battery only) appear to be the predecessors to this range using the DK91 DF91 DAF91 DL92 tubes but with geared tuning drive unlike P114BQ, Invicta28/29 and PAM712/716. (all DK96, DF96, DAF96 and DL96),
