I have many 78s and love them all!!!!
Several DECCA and a whole album full of "18 Top hits" .. I have 2 FULL SIZE 78s (Same size as a 33) and I have one ONE SIDED 78 from 1912 I believe....... (Nothing on the other side)
If you like 78s,here is a whole directory of 78s someone put up for ppl to listen

Its not as nice as having the actual 78 (Analog) but its ok...
