The 9,3X47R Express was not a dedicated 9,3X47R Express Barrel in the initial German Express Proof Tables(1891(1893)-1939), so the individual offering the Platform w/ Express Barrels for proof must provide in writing load data as well as ammo to the Proof Master free of charge.
Regarding the Express Barrels, there were smooth bore as well as rifled. The table begins w/ 12 bore; has 20 bore then 24 bore(0.577 Express) is noted both for smooth bore as well as rifled as well is 37 bore, which is noted as 0.500 Express. The British 0.450 Express is 51.05 bore(11.43mm).
12 Bore
20 Bore
24 Bore - Both Smooth & Rifled Express Barrels
37 Bore - "
51.05 Bore(11.43mm) - "
Another Reference gives the above plus
72.68(10.16mm) bore &
99.7(9,14mm). So, I guess the 9,3X47R may fit this profile and more than likely was a later addition to the Express Barrel Proof Table.
