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. 1. cylinder (1 pegs) 2. beveled (various) 3. lettered (1 square peg per letter) 4. Clear Window blocks (in 1,2,4,8 peg sizes) 5. "thin" blocks (about 1/3 the width of a lego block) 6. Blocks with a hole of a wheel and of course the wheel. 7. partial-circle/curve parts
