Germany, 1842: Estimation of Russian Output

Apparently, Russian Weights/Prices translated into German:

Where 1 Prussian Unze of 2 Loths is (2 x 14.6159784485459 Grams) 29.232 Grams = 0.939829251 Ozt, and assuming the Prussian Commercial Pfund, 1 Kilogram platina cost Thlr 106.90.  At this Prussian-Weight, 1 Poud Russian platina cost руб Ag 1,598 
and 1 Poud Platinum cost руб Ag 4,090.60.

If the Russian Weight of 1 Funt (409.512 Grams) was intended, then 1 Poud Russian platina cost 2,000 Thlrs or руб Ag 1,825.


c. 1840:  1 Troy Ounce platina (US Low: USA importer's bulk) ~ руб Ag 3.471

c.1841/2:
 
1841: 1 Troy Ounce platina (ore) = Preuss Thlr 3.325 (USD$ 2.33) OR
1841: 1 Troy Oz. platina (ore) = Preuss Thlr 3.7976 (USD$ 2.66)
1841: 1 Troy Oz. Platinum (refined) = Rthlr 8.51 (USD$ 6.) 

1841: 1 Troy Oz. platina (SPb: Russian ore) =  руб Ag 3.034
1841: 1 Troy Oz. Platinum (SPb: refined) = руб Ag 7.767368

This estimation of Russian ore appears to be intrinsic :

c.1842: 1 Troy Ounce Platinum (intrinsic?) = Thl 8.87 (USD$ 6.12)
