I have handled both in a local AD here in Hong Kong, both are not marked as T25 and the Arabic appear to use even more tritium vials then the Roman. Another odd thing I notice is that Ball-US website said that the US version of Engineer II Arabic does NOT have the 3 and 9 numerals! I have never seen an Engineer II Arabic that does not have the 3 and 9 numerals. Could anyone confirm that such thing really exists? And if it does exist, does the missing tritium vials on the 3 and 9 numerals exclude it from the T100 list?
