Hi Geoff,
The E prefixed Club is one of the rarer varieties of the Airsporter design and rarely encountered today. It did indeed have a shorter cylinder. The forend was also shorter than the contemporary Airsporter's by 5/8 in. The barrel was tapered just like the Airsporter and trigger adjustment could only be carried out with the stock removed. The rifle had a ‘Shell’ shaped cocking lever release catch and the same turret backsight as the Airsporter. The stock flare on Club models starts in front of trigger guard too. The E prefixed Club was made between late 1948 and 1950, when the cylinder and stock length were increased to that of the Airsporter. According to The Golden Century by John Knibbs, only 2709 of these rifles were made.
I bought the last one I saw for sale and that was a couple of years ago. The rifle shoots very well - I'll bring her to the club one evening as it has been a while since I last used her.
Kind regards,
John
