As to the US not offering the Nordern to the RAF it was
just as much a factor that the RAF did not consider that
tachometric bombsights such as the Norden, and British
ABS Mk 2 were suitable for night bombing from medium
altitudes. As a result the main BS used bu bomber command
would be the Blackett (MK XIV) which was simpler
and did not require as long a run up as the Norden

Uh, the Brits DID use the SABS Mk.IIA from 1943 for precision bombing
(in clear weather, of course)!

The SABS MkII was used in relatively small numbers. At the peak
of its use it was used by only 5 squadrons and in those only 3
aircraft in each were fitted with the SABS. Most were withdrawn
at the end of 1943 and only 617 Squadron was equipped
with the SABS MkIIA IRC

The problem with the SABS was each one was effectively hand made
and the training required to use it effectively was much more intense
than for the MkXIV . ISTR that even the bombardiers of 617 squadron
who were selected from the best available had to have special
coaching to use it effectively. Given the emphasis on area bombing
this was not regarded as justifiable for most units.
