Halifax dataplate

Hello,

This dataplate was found years ago in the crash place of Halifax W7813 (TL-P) shot-down by night fighter ace Oblt Wilhelm Telge (12 victories, Staffelführer of 5/NJG1) over Gruitrode (Belgium) on the night of 25-26 May 1943.

My question is: what kind of dataplate this is? Airframe? Main? I understand that « 57 » stands for Halifax, but what about the rest? Is this maybe a Handley Page serial? And if yes, is it possible to establish a correlation with W7813 from this number?

Any help welcome. Thanks in advance.
