It is a 3.5" barell and a glossy dark blue finish and does appear to be the original handle on it. Would that still be in the $800 range?
A quick review of completed auctions on Gunbroker shows four 3.5" pre 27's that sold from $1300 to $1800. One for $1450 did not sell.
Now, that doesn't mean yours is worth that much but without pictures and a really good check out that's all I can offer.
