Igor, the RAF Sabres were built by Canadair, and were CL-13 (F-86E).
A total of 430 were built, with the engines and some other components funded and supplied by the US, and the airframes built and paid for by the Canadian Government.
The first three, serial numbers 19226, 19236, 19239, were F1's, later re-designated F2 to be in line with Canadian noemclature, and were given RAF Serials XB530- to 532. The remainder were Sabre F4's, serial numbers in the XB500 to 900 series, with 60 aircraft intended for Fighter Command in the XD range, although these were moved around later, due to losses, shortages etc.
The bulk of these aircraft were intended as a stop gap, until the Hunter arrived, and most went to 2 TAF, RAF Germany, eleven squadrons being deployed there, with only two squadrons remaining with Fighter Command in the UK, and the aircraft were delivered, by air, from the Canadair plant by RAF Ferry Command, in an operation known as 'Becher's Brook' (named after the famous Grand National jump at Aintree race course), between 8 December 1952 and 19 December 1953.
Roughly half of the aircraft supplied were fitted with '6-3' wings, the remainder with slatted wings.
When the RAF took delivery of the first Hunters, the surviving Sabres, being the property of the Canadian Government, were returned to Canadair. As you know, the Italian Air Force took delivery of re-furbished aircraft, all from RAF stocks, and some of the ex-RAF aircraft might have been sold to Yugolsavia - but any sales and conversions were the concern of the Canadian Government, not the RAF.
In the early 1960s, I saw a number of the remaining stocks at the RCAF Depot at Prestwick, Scotland, still cocooned for shipment, alongside other types such as Avengers. A few years ago, I re-visited the crash site of two No.66 Sqn Sabres, in the Peak District, not far from where I live. The paint work, although more worn than when I last saw them, was still in fairly good condition.
Sorry to take up your space Paul - back to the thread.
