(Frog incorrectly colored black in this illustration.) The company adopted the use of a highly polished nickel plating for the lever caps of its premium bench planes and displayed the company name on them surrounded by bright red paint.
The other way chosen to distinguish the bench planes was the promotion of the design of their jointed lever caps.
They do not bow the blade a bit, like the #80A regular scraper blade, made of softer steel so that its edge can be rolled over, is held in an adjustable (pitch) holder.The standard lever cap used by competitors applied pressure to the chip breaker/cutter assembly at two points—one at the point of contact with the cap’s cam lever, the other along the lower edge where it made contact with the hump of the chip breaker.The hinged cap was designed to apply force to the chip breaker/cutter assembly at a third point, just above the chip breaker hump.First model Bedrocks were numbered 2 thru 8 and only the 3 line Bedrock Cap and frog design distinguished them from the regular line of bench planes. It has the proper 3 line Bedrock cap, round sides, 1 screw frog adjuster and low front knob of a type 4. Everything else about this fine 607 jointer plane is Like New / Fine and all original. He applied his trademark coat of clear lacquer to protect it from rusting and put it in a glass front case he made for his collection. The type 1 / 2 Bedrocks had the special new mated frog design but were numbered with just a single number.Stanley soon changed their numbers to be the 600 series to set them apart form the standard line of bench planes. Over the years the Bedrock name on the lever cap changed from a 3 line Bedrock cap, to a single line Bedrock, then to a short lived 2 line version. The other distinguishing feature of these early Bed Rocks is that there is a milled out area where a patent date that was in conflict with a competitors patent was ground out. It has been lightly cleaned, and has a rich dark patina. A previous owner did scratch his name on the side with an electric pen.
