Frame Numbering

This is a listing of known frame numbers identified between 2001 and 2007 - some numbers have been ignored if they do not conform to the following conventions:

Production Quantities

At Padiham if we assume 100 frames were built in 1945 (wartime), 700 in 1946, 900 in 1947, and an unknown quantity in 1948 then we get a total of 1700.
Add to this an assumed 1000 frames in 1950, 600 in 1951, 600 in 1952, 400 in 1953, 100 in 1954, 100 in 1955, 50 in 1956 we get a total of 2600 to 3000 but can this be correct?
If we assume three framebuilders at the peak producing 1000 frames per annum this equals 7 frames per man per week!
Blackpool numbers run sequentially with the third (or third and fourth) digit being the month totalling approxiamtely 400.
For Example frame number 826346 would have been the 346th frame made in the June 1982 (82-6-346)
Therefore estimated total production comes to 1700 + 3000 + 400 = 5100.
The number of frames on the register comes to just 115, which means that, if 25% of frames were exported, only 2% of frames manufactured have been found so far.
