Would it? I doubt it.
The blank order form has a 38 Special on it for $16, 95 and a 38 S & W for 29,95 which is at least a bit confusing.
Having said that, it doesn't really matter as the mail coupon in the advertisment is completely different from the one Hidell used, which of course means that the advertisment itself also can't be the one from which Hidell ordered the revolver.
