Here is a selection of items you could get from the Sears catalog, once upon a time.
Sears dropped Silvertone as a brand in 1972, but Samick (Korea) bought the name in 2001 and started a new line of instruments, including some reissues of the old models.
This started as a vintage neck that I got on eBay. I built a reproduction body and hunted-down old-style parts to rebuild this as authentically as possible. The finish is black nitro, which is accumulating nitro damage just from existing. Someday I should strip that garbage off and re-shoot it in polyurethane.
This is another factory guitar, vintage 1960s, made by Danelectro and sold exclusively through Sears. The 1448 was one of the cheapest electric guitars in the Sears catalog, but it came with something special - it's own amplifier built into the hardshell case. There is almost no wear on this guitar, I don't think it was played much.
This is the big brother to the Silvertone 1448, vintage 1964-67. Construction is basically the same, but with a full-scale neck, two pickups, and a much better amp. For a lot of details, see the 1448 page. This guitar is in excellent condition for being almost sixty years old, and apart from cleaning and re-stringing, it needed nothing.
The Silvertone 1450 is a relatively rare model from 1965 to 1967. It is identical to the much more common 1452 "Amp-in-Case" model, except that the 1450 has a three-ply tortoiseshell pickguard in place of 1452's white masonite, and the 1450 did not come with an amp. The three-bolt neck attachment indicates that this is a fairly early example. There should be a date stamp inside the neck pocket, but I don't want to take it apart. For a long time I thought this was a 1452, I was quite pleased to discover while writing this that it is actually the more deluxe 1450.
After successful and interesting experiments rebuilding 1448 and 1457 "Amp-in-Case" amplifiers, I thought I'd try something bigger. So I kept an eye on the eBays, and eventually came up with this - an early production Silvertone 1472, made by Danelectro and sold through the Sears catalog. It was fairly cheap because it wasn't working. However, the cabinet is solid, the aluminum faceplate and labeling are in good shape, all the knobs are there, and everything else can be replaced or rebuilt. The Tolex is in very good shape, and the corners of the cabinet are all pretty much intact. Much like buying an old car - a blown engine is easier to fix than a rusted-out body.
This is a Harmony-made Sears Silvertone 1478. This body style was originally called the "Silhouette", and Harmony sold similar models under their own name. Later it became known as the "Bobkat". I can't find a serial number anywhere, and I'm not taking it apart to look for one, so I don't know the exact age of this guitar.
Danelectro is my favorite type of guitar, simply for the genius of their unorthodox, inexpensive, yet highly effective designs. I love the tone of old-growth masonite. If you are looking for details, the Pro-1 Bass is the most complete build documentation.
The skunk stripe is the walnut strip down the back of many 'classic' guitar necks. It is an indication of the type of truss rod within: A single steel bar in a curved channel. To create a perpendicular force, a truss rod needs two members: one in tension and one in compression. The skunk stripe rod uses the neck itself as the compression member. This was originated on a guitar neck and then extended to the bass. The problem is, a bass neck is much longer and less stiff than a guitar neck and is under much greater compression. The last thing you want to do is add more compression. Also, using two dissimilar materials for the two members inserts a host of issues, and using steel against wood, that's just hideous. The wonder of the skunk stripe is that most of the time you get away with it, despite how awful the design is. Of course, it is very cheap and easy to manufacture, in a factory setting.
