If you are talking about electrical it would be an Electrical Schematic..
It depends on the purpose and type of the drawing. If the scale would be necessary for proper interpretation of the drawing (e.g. mechanical drawing, plans for a building) then yes. If the scale would not help in interpreting the drawing (e.g. electronics schematic, software data flow diagram) then no.
Personally I would contact Daisy directly. They offer a free service to tell you about your old Daisy. See the link below.
A schematic drawing is a drawing that shows you the parts of a system without going into too much detail so as to overwhelm the person who is viewing the drawing. For example, an engine wiring schematic would show the distinct colors of the wires (such as red, blue, green, etc) and how they run from one part to another. The parts would not look like actual parts in the schematic, but would be represented by squares, circles, and other shapes with the part name written on them. This is to help show how something works without making it too difficult to understand. Another good example would be the map you would see at a typical mall that displays where different stores are and uses symbols to show the nearest food areas, bathrooms, and exits.
Savage would be a good place to start. E-gunparts.com might have one also.

An inspection drawing looks like/is a schematic, detailing the exact mechanical layout of a factory, building, etc ... A production drawing is an illustration of what the buliding would look like, if it had yet to be built/dressed. Think of a movie set. The production drawing would show you what the space would look like, complete with specific lighting and people included, to give a sense of scale.
This pistol was made from 1979-1989. If you would like an estimate of value then you need to state the condition of the pistol from Poor to Excellent. With out that information it is not possible to give you an estimate of value.
I would contact Daisy directly and ask them See the link below
To make things simpler! Imagine if they had to draw an actual transistor or battery everytime... that would have been both time consuming and difficult for the person studying the diagram ( as one engineer's drawing of a transistor may be totally different from others )
I would start by checking the web under "Air Gun Repair" or see the link below.
A schematic would be located in a service/repair manual.
