Stay clear of this one, it's an unusual fantasy badge that generally comes under the catch all title of the 'Mutant Fake'. These are badges that have a non sensical mixture of one type of obverse design and another rear set up from a completely different design or maker. In this case it's what appears to be a type 5 Souval design obverse matched with a type 1 unknown maker reverse known as the 'Juncker Set Up'.
There are several variants of mutant fakes that have been catching out dealers and collectors for years, and this is one of the rarer ones. Other types include a type 4 design B.H.Meyer/Frank & Reif obverse and the same 'Juncker Set Up' as above.
Here's a poor couple of pic's of one the same as the one you show, but you get the idea.
'I do not think we can hope for any better thing now.
We shall stick it out to the end, but we are getting weaker of course, and the end cannot be far.
It seems a pity, but I do not think I can write more. R. SCOTT.
Last Entry - For God's sake look after our people.'
In memory of Capt. Robert Falcon Scott, Edward Wilson, Henry Bowers, Lawrence Oates and Edgar Evans. South Pole Expedition, 30th March 1912.
