Burgo catalogue 1952-1953.
John Griffiths, author of <i>The Encyclopedia of Spring Air Pistols</i> identifies the following pistols as:
<b>Model P/A.II The Koma LDP4, which went on to be called the Voere LDP4 around 1955. One of the worst air pistol designs ever IMO.
Model P/ A.5 JGA (Anschutz) air pistol, which became known as the JGA 100 after 1960.
Model P.6/A Jung Roland air pistol. A very rarely catalogued pistol in my experience.
Model P.6/B BSF S20, basic model</b>
Interestingly, this catalog lists makes, models and prices also sold by Burgo but marked under their own brand:
