There's no particular sequence or logic to the planes I'm featuring, by the way; just what I found on the shelf that looked interesting.
First, another one of Stanley's simplest planes, the 110. This is a long-pattern (7-1/2" long) high-angle block plane.

People assert that Stanley's block planes came in standard angle (20 degree bedding) and low angle (12 degree bedding); but, oddly, some of the cheap block planes came with higher bedding than the standard angle. I forgot to bring the protractor in, and am NOT going out to the shop in this rain, but other high-angle planes I've measured have been about 23 degrees.
This, at any rate, was surely marketed to the homeowner who was convinced s/he needed a block plane but didn't want to, or couldn't, spend real money on one. There are five parts: body, wooden knob on the front that screws onto a threaded boss on the front, cutting iron, lever cap, and the screw that tightens the lever cap down. Adjustment is by feel, and the iron, not needing any slots for adjustment mechanisms, is just a piece of steel: tempered, flattened, logo stamped at the top, bevel ground. The knob, surprisingly, is rosewood in the early years, slowly becoming a cheaper, coarser piece made from cheap wood.

I picked this one up a few years ago for 50 cents or so because one of my maybe-someday projects is to make a piece of furniture or two with the simplest kit I can assemble, and this is the ideal block plane for such a project. First, of course, I have to finish all the projects on the house (ha!). Woodworkers get all over themselves with Have to Have the Very Best - I'm not immune - and I think it would be fun to find out how good a piece of furniture I can make with Less Than the Best.

John, of johnsironsanctuary, has posted about one of the "transitional" planes from Stanley, the No. 27 (page 3, reply 34:
http://www.papawswrench.com/vboard/index.php?topic=9443.msg63036#msg63036). I don't much like the term "transitional," because Stanley actually offered these concurrently with the metal-bodied planes. Stanley's catalog No. 110 introduces them by saying, "Every Carpenter needs two or more wood planes in his kit, for rough outside work." I think the reality is that some carpenters preferred the feel of the wood body in general; and the jointer planes are a lot lighter than the all-metal ones. I consider "hybrid" a more accurate term, as they combine a wood body with the Bailey adjusting and lever cap mechanisms.
At any rate, let me show off what I consider the prettiest of the hybrid planes, the No. 36 smoothing plane:

Notice the "razee" mounting of the tote, dropping it down lower than the rest of the body, presumably to focus the thrust on the cutting edge (I believe "razee" is adopted from shipbuilding, where it refers to a ship with one or more decks removed). This, and the coffin - curved - shape of the body, make for a really pretty plane. I found this at a rummage sale at the local historical society years ago, under a table until I saw it, at which point it was magically in my hands. I haven't actually used it, other than to try it out; it's one of many planes I want to try out when I get out from under this fix-the-house project that's been going on forever.
Some years back, my bride and I went to a silent auction fund-raiser of some sort. On the wall was a photo-realistic painting of a No. 36, lit for maximum romance. I can't recall what the bid was when I saw the painting, but it was a lot more than the $10 I paid for my cellulose-and-iron version. I tried to gloat just quietly to myself.
The iron beds on the wooden bed and the modified Bailey frog, both; so the frog's adjustment slots are there just to get the iron frog aligned with the wooden bed. There's no mouth adjustment; for a tighter mouth, you'd have to put in a patch; looser would require a rasp and file.

People say sarcastic things about these, which puzzles me, since a lot of woodworkers are fanatical about all-wood planes, which have the same issues with warpage as these but more awkward adjustments for the iron.
