Hi Larry,
I've checked the losses for that night and obtained this information ( the most probable if we consider that that bomber crashed near Bayreuth ):
Hampden P4365 Information
Hampden

Further Information
"Serial range P4335 - P484. 50 HP52 Hampden Mk.B.1. Part of a batch of 120 Hampden B.1. P4285-P4324; P4335-P4384; P4389- P4418, of which:- P4304; P4306; P4312; P4315; P4347; P4369; P4373; P4395; P4401; P4418 were converted to Hampden TB (Torpedo Bomber). P4335 was the first Hampden fitted with a balloon cutter. Delivered by The English electric Co. (Preston) between Feb40 and Aug40. After the 'L' and 'N' serial numbers, which were mainly allocated before the outbreak of hostilities, serial numbers do nmot run continuously s small groups of numbers were deliberately omitted. The object of this subterfge was to confuse the enemy in regard to the actual number of aircraft being built. P4365 was one of two 144 sqdn Hampdens to be lost on this operation. See: P4291. Airborne from Hemswell to attack the Leuna oil refinery. Destroyed in a fatal crash on return to base. Cause not established. S/L P.H.Rebbeck KIA P/O D.Hutchins KIA Sgt B.H.Foster KIA Sgt H.Dickinson KIA "
If you want, you can cross-check the information and obtain ALL the other bombers that went missing from 16th to 18th August 1940 on this site:

PS: From one of the pictures, it seems the engine is a radial one...( I only had a glance at it...not very carefully though...sorry...but this is an interesting point ).
