People ask for valuations because they are hoping they will be told it is worth "MORE" than they "THINK" it is... they will list it at what they originally thought if they are told it is worth less... they will JACK the price if they are told it is worth more.
Personally, I think these types of posts are just cross-promotion fishing... hoping to receive offers by PM... how hard is it to type the model in google? Surely easier than posting... and how long does google take? Surely faster than waiting on CGN geezers to type responses...
I remember some time ago, a youngish fellow found an old Win pre-64 .30/30 in his deceased grandfather's home... he thought; "Pre-64! This is gold!" He asked a valuation question on the Hunting & Sporting Arms board... he said it was the "rifle" in "excellent" condition, a few responded with numbers (high)... some asked for pictures... when the pictures were posted, the gun was a "carbine" in poor condition... the posted numbers dropped exponentially... the young fellow listed it at the highest "pre-photo valuation" without pictures, described as "excellent" condition... I decided to stop giving valuation quotes... UNLESS I can inspect the item in my hands. JMO.
