I need some help

Always said i wanted a beetle one day when i am a grown up. And now i have one. Unfortunetly it came in more then one piece.
I need help in identifying the engin. Not sure if it is a 1200 or an 1300 as the boot lid (with 1300 badge on) is not the OE one. After talking to friends and a lot of google, we think it might be an 1957.
If someone can assist me with identifying the year model as well as engine capacity.
The engin "nr" is sffr04056
