M4 Enigma Cabinet
The Enigma cabinet shown here is made of Red Oak, but the actual material used in Enigmas was Quarter Sawn 'Weiße Eiche' (Deutschland White Oak). This is based on my research on the M7772 Enigma made by Heimsoeth Und Rinke. I am sure there were other woods used by other manufactures. But the reason Quarter Sawn 'Weiße Eiche' was desired was that it resists cracking and moisture. Great for Naval use.

 In England they call it European Oak which is slightly darker.

A new cabinet is being made with 'Weiße Eiche'.
