Anyway...
A silencer (DB/1 - Lab' item number 23) was at the lab' from 30th August 1985, inside which was found the crucial flake of blood that was discovered trapped between baffles one and two - which led to that flake being tested and examined between 12th and 19th September 1985, which produced the crucial blood group activity, A, EAP BA, AK 1 and HP 2-1 - and this could not have been the very same silencer, which EP still had in their possession, from 11th September 1985 until either 20th / 26th September 1985, at which stage that silencer was sent to the Lab' to be checked for fibers, blood and to be fingerprinted?
Both silencers, could not possibly have been one and the same silencer - because silencer (DB/1 - Lab' item number 23) had already, presumably, have already been checked for blood and fingerprinted...
By and from 15th and 23rd August 1985...
Do you agree, or not?
