The first of this variation of the FL6 had the brass plate instructions soldered to the tank, then came the instructions on a transfer (as in the first photo), so I’ll revise my date to 1940s to 1960. Tony
Funny thing about the FL6 is that there are so many of them around and every one loves them but there are so many things we still don't know about them. When was the two piece case and the one piece case. When they went from welded box to riveted box. When they went from old tank to new tank. When the brass plaque ended and the transfer started. Many of us here can have calculated guesses with plus or minus 5 years but I think it strange we can't do better.
David, I was very precise in saying, above, “...the first of this variation...” because I was excluding the ‘thin’ pump (of which I have one; 1937). Cheers Tony
Yes, Tony - and I was merely adding a little elucidation for Sidney Harbour (is that really his name?)... As far as I'm aware, version 1 (brass plate, long thin pump was 1937-38; version 2 (brass plate, shorter fat pump) was 1938-39 and version 3 (transfer, shorter fat pump) was the back half of 1939 onwards. Until when, I don't know... Edit: Getting out my paperwork, I have an advert for the FL5 dated December 1936. Then I have an advert showing the FL6 and dated June 1937 showing "The new 1937 model TILLEY floodlight projector". This has the long, thin pump. The same or very similar images appear in November 1937, September 1938, August 1940 and November 1944. The first dated advert I have showing the shorter fat pump with T-bar handle is not until December 1948. I have a suspicion the pump had been changed earlier but the same FL6 illustration appears throughout the war and beyond - possibly a result of Tilley not changing the illustration until after the hostilities i.e. they had other things to concentrate their minds upon 1939-48...
1939-40 @Mackburner @Henry Plews @Tony Press @David Shouksmith @JEFF JOHNSON Hmmm change that to 1940-41
