Very long shot. Looking for details about a Luftwaffe bomber attack May 10th 1941 - Stoke Works, England

[Mysticpuma]

I have information that on May 10th 1941 at 2.10am the Salt works at Stoke Prior near the town of Bromsgrove, Worcestershire, UK was attacked by Luftwaffe bombers.

At the time the Salt Works (from data published at the time) produced 14% of the world's industrial and digestible salt and must have been seen as a relevant target for the enemy to attack.

The actual damage to the Saltworks is not known to me unfortunately (but I am still researching that) but it did create quite an interesting side effect.

One of the bombs dropped failed to explode and when UXB crews excavated the site in order to diffuse it, they found evidence that proved salt had been mined at the site in an open-cast method previous to any history recorded,

The bomb had actually dropped into one of the shafts that had been previously worked at the site and remained unknown until the Luftwaffe 're-opened' it.

I'm just wondering if in any of the records available for that or dates very, very close, may detail what aircraft were used, what unit flew the mission or if any other reasons are known as to why that should be seen as a target?

I do know that there is a nearby rail-line that leads to Birmingham and on the route in it would have gone past Longbridge works (aircraft were built there) and also a Wagon works in Aston Fields which repaired many of the locomotives and rolling stock for the Birmingham area.

I'm just interested in-case the information is known?
