As the linked topic says, yes, it did.

 

Locked for now.

Okay, unlocking, now that I have more info at hand.

 

Most (if not all pictures of Hurricanes have this label present. Also, here is an excerpt from the construction drawings (electrical schematic):

 

 

Also, in the Soviet Hurricane flight manual, the part about the buzzer is underlined:

 

Also, to note, for example, this picture (from AP1564B&D)

 

The buzzer is visible here between items 12 and 14. Also, the throttle is the late type with a bomb and rocket firing button:

 

This is a Mk.IIa found in Russia. The buzzer is visible: http://109lair.hobbyvista.com/DETAILSITE/UK/hurricane/z2768/hurri_z2768.htm

Most likely, there were numerous variations, and perhaps the buzzer was dropped after some time/or it was dependent on the airplane operator, or possibly it was deleted (or even added) with a technical order.

Luke took that personally.

When on the topic, does anyone know when the Hurricanes started using the higher manifold pressure (14 lbs)?

 

According to Chat GPT, the British always used it as long as they had 100-octane fuel, and the Soviets from 1943 (probably not accurate).

Late 1942/early 1943 IIRC in the USSR.
