Standard Catalog of S&W is the bible for that brand, except the pricing is useless. None of the other "standard catalog" books are good for much. Surely not worth those asking prices.
I totally agree the Standard Catalog of Smith and Wesson is the bible for that brand. Except for the pricing of course. Almost everything you could possibly want to know about Smith and Wesson products from Horace Smith and Daniel Wesson's development of what became known as the Volcanic firearms staring as early as 1852 right up to the present day. Well, as I said before I prefer my 3rd edition which was published in 2006. I am not interested in anything S&W has done since 2006.
I will disagree slightly about the other "Standard Catalog" books. Although clearly mimicking the Smith book, and published by a different outfit, I do find useful information in the other "Standard Catalog" books.
I used to look down my nose at the HWP/28, back when a good 27 or 29 was $400 and a 28 was under $300 but time changes everything.
The Model 28 was introduced in 1954 as a 'utility version' (quoting from SCSW) of The (N frame) 357 Magnum. When introduced it was called the Highway Patrolman, changed to Model 28 in 1957. The Model 28 lacks the high polish of the Model 27 and does not have the checkering on the top strap and barrel rib.
I have three of them.
Although the finish of a Model 28 is not as bright and shiny as a Model 27, this one has actually been refinished and looks to me it was sandblasted.
The Highway Patrolman marking can still be seen on the barrel.
Also, the Model 28 has the Baughman Quick Draw front sight. The Model 27 has the Patridge front sight.
As has been stated several times, the Model 27 retains the checkering on the top strap and barrel rib of the original Registered Magnums. My Model 27 is in the foreground of this photo, a Model 28 is in the background.
