What you have is a classical SP 109, upgraded to BA, even already with the S-Wing poppet, newer Diaphragm and Diaphragm Cover.
The exhast valve is the correct one for the SP 109/150 models.
Everything looks quite okay. Your 109 (BA) is from 1989 and the missing chrome inside the body is no issue, mostly there is anyway no chrome at all.
Just clean it and you will be fine.
I have many SP 109 metal orifices, so just contact me.
Anyway, nice reg.......
