Model No: 34
The Stanley engineers level number 34, also known as Stanley 34 machinist
level was produced as a high precision, sensitive level.
The level is fitted with a long, large diameter, ground glass bubble and has a base which has been milled true. It is the combination of these two elements which make the level very accurate and as such suited to engineers/machinists.
The bubble is housed inside a tubular metal case which has a rotating hood to cover the bubble when not in use or when it is needed to be protected. This hood was named by Stanley as the "Eclipse Cover".
The tubular case is held suspended with the use of a screw at either end which screw directly into the base. These screws can be used to make adjustments to the level.
In the earlier years there were two types of Stanley number 34 levels produced, one numbered 34 and the other 34G. Both types look identical from above, however when the levels are turned upside down, the Stanley 34 has a flat bottom and the Stanley 34G has a groove running through the center of the base.
The level was produced in four sizes: 4", 6", 8" and 10".
In the 1950's (possibly earlier?) the Stanley level numbers 34 and 34G were no longer produced having been replaced with the level model 34V.
The Stanley 34V level had a groove in the base and was also produced in the same four sizes at the previous models: 4", 6", 8" and 10".
