Photocopy of substitute certificate of destroyed original

My grandparents were married in Taipeng, Perak (Federated Malay States) in August 1941. The record was filed at the office of the Registrar of Marriages in Taipeng. In December 1941, the Japanese invaded and destroyed the repository. My grandparents were issued a replacement/substitute certificate. I currently possess a photocopy of this certificate. I think I may have the last surviving copy. How do I go about citing this? Thank you.

Interesting item!  EE would cite this as an unrecorded record, privately held. EE 3.24 and 3.25 give a basic review of the principles; 3.34 illustrates "Legal Documents, Unrecorded Family Copies."
