Hong Kong replacement?

Hi,does anybody knows if that one is a replacement?

The Banknote Book lists it as a normal note.
B658 l. 31ST MARCH, 1947. Prefix X - Z, A/H, B/H.

I agree with you

According to the issuing bank (The Hongkong and Shanghai Banking Corporation), the HK$10 note attached to your email is not a replacement note. It is a general banknote with a prefix "Z".

that is the response from Public Enquiry Service
Hong Kong Monetary Authority
Thank you
