:lol: The spacing of the grooves ( although it is only one continuous groove ) on an LP were quite wide apart. They were also made of a more coarse material. When they introduced the 7" records the spacing was finer. Therefore from memory if you used the needle for an LP on it, it would skim across the record resulting usualy in damage.
 
Mine were all LP or 78. The 78 stylus being about twice as wide as the LP stylus.

The LP stylus would play 12" and 7" records equally.

Interesting (possibly) fact about 78 RPM records: These were made of shellac and played with steel needles. Normally the needle would wear out the record very quickly but the shellac was loaded with carborundum powder which is the stuff emery board/paper is made from. This reversed the process and made the record 'sand down' the needle as it was playing, preserving the tracks recorded on the record.
