Sd.Kfz 8 with 88mm Flak 18 (Self-propelled gun)

[Louis]

The 8.8 cm Flak 18 (Sfl.) auf Zugkraftwagen 12t (Sd.Kfz. 8), also known as the Bunkerflak was a German Wehrmacht Half-track self-propelled gun developed before the war and used in the first half of the conflict. It was used during the invasion of Poland but is best known for its use during the Battle of France, where it was the only German self-propelled gun capable of destroying the heavier Allied tanks such as the French Char B1 and the British Matilda II. Remaining vehicles were used on the Eastern Front.

Only built 10. The last Bunkerflak was destroyed in 1943.

I wonder why only 10 were made.
Seemed like a good idea really.
