What are the different specific "types" of LEGO blocks that have been manufactured? I am not talking about any of the action figures or themes. Is there some type of list, as to type, size, colors?
Are they still available for purchase?
I was especially interested in the following that I have not seen in awhile.
- Cylinder (1x1)
- Beveled (various)
- Lettered (1x1 per letter)
- Clear Window blocks (in 1,2,4,8 stud sizes)
- Plates
- Blocks with a hole of a wheel and of course the wheel.
- Partial-circle/curved parts
