well, checking webster on line i find:
Extrinsic: a: not forming part of or belonging to a thing : EXTRANEOUS b: originating from or on the outside; especially : originating outside a part and acting upon the part as a whole
Intrinsic: 1 a: belonging to the essential nature or constitution of a thing
i've no clue what you thought i meant but i know exactly what i meant when i wrote it. and in the example i cited, the BSW had INTRINSIC value because of the way it was built and finished compared to the other 2, especially so when taking into account the cost. EXTRINSIC would - to me - be value ascribed to something independent of it's form/function, i.e. it's name. something extraneous (note the synonym in the definition) to the guns design and build quality. something that adds nothing to it's ability to function.
intrinsic is form and function. it's able to do what is going to be required of it in a reliable, competent manner. that's where the personal aspect comes in. someone may want a particular item because of the name on the barrels and never expect it to do anything but sit in a rack. others may not care what name is on the barrels as long as it can take the heavy use of competition trap or the weather of a duck blind or whatever the need it's filling. for some people a marlin model 90 could have greater intrinsic value than a purdey.
