Its mfg date seems to be 1972. Reims Cessna F150L msn F15001090

Note that the photographer mentions another 150 fuselage with same registration, 'in the rafters'.

If it is indeed another 150 fuselage F-BUMA, then the airframe in the first photo - link above, may be a composite rebuild, and the mfg date may not apply.

Just to add some confusion, there is or was a Cessna F172 (msn F17201034) also with the same registration (F-BUMA). Fate??
Just my 2 cents..
