2 Vintage/Antique EWA Pottery Ozark Ocarinas Key of C & G & Instructions

Description

Here is a lot two Antique/Vintage 11 hole EWA pottery Ocarinas.  Both have an abbrevated EWA marking and a white label with Czbomo-Slovenia printed it and located on the top. It is a mystery to me and I can only speculate it is a "property of" identification. The larger has an engraved C (key)and a 6 below. The larger one appears to have a crack running around its curcumference. It could be a repair but it would be a miracle repair becasue of the size and it could be argued that it is a fracture. I cannot say for sure. It seems to play (I am a non-player) and is sturdy. The smaller one , G (key) 3 below is in better condition with wear from years has a similar label and the EWA marking. Additionally, there are 3 printed sets of instructions, titled in French (Methode L'Ocarina). However there are 3 to 4 different translations  of instructions in most of the illustrative panels with diagrams. The paper is interesting material. It seems to be a cross between Parchment and Onion skin. While there are English and more recognizable languages in the various panels I enclosed a photo of whats on the top of the page. Please review  and reach out with any questions. Thanks.
