Hello again guys well this is what I found out. I have many sources now on what realy item is as we said cartrige box, or greese box to maintain guns that used to have hard leather inside also, the age of item is aprox 18-19 centoury not earlyer aprox worth based on pictures around 350 euros, valued by one man that works for one of UK AH-s.(its going realy slow with e-mails)
Now origin isnt realy Turcish it is Balkan since this area where I live used to be under sige of them for long time so people known to use their
ways of crafting for some time but when Ottoman Empire was gone people here started to use their own ways of crafting etc. I am still doing some diging around since info I gather seems incostitant one man even said it was used on horses to cary flint the same man that said the rock is
just a glass a jewler. Now only thing I want to ask you guys is do anyone maybe know when that type of cuting and forming glass first apeared, far as I know realy early. Tnx once again
