Breguet 691 Engine Cowl ?

Apologies for the repost – my spelling is not up to it!

I believe that this Engine Cowl is from a Breguet 691.

The number 50 is painted on the inside – so I assume aircraft number 50. From 72 onwards they were 693’s Only 230 were made before the Fall of France.

The distinctive large holes in the cowl are for ventilation of the Hispano Suiza engine used in the 691.

Can anyone confirm my Assumption ?

N.B. The bolts inside have a letter L cast on the head. No other stamps or markings. It was recovered from near Toulouse
