1981 GLS 1.5 (I think) engine and 4 speed box

Bare 1.5 (I think) engine and 4 speed manual box. 
Condition is completely unknown coming out of a 1981 golf cabriolet which I haven't heard run or drive. 
It's still in the vehicle looking for £50
Carb and shafts not included. It's just the bare engine, head and box. 

The head is from a 1.8 as it's got the water pipe coming out between cylinders 3 and 4.
1.6 heads it's between 1 and 2.
There should be an engine code just below no.3 spark plug, possibly EX engine?

Thanks. Had a look. No markings below no. 3. 
Where abouts on the block would it be? Cheers

Ah found it. "E7"

I think you will find it's a EZ if you clean up the face a little more.
Engine codes can be found on the web,

Cheers
