Hi Richard,
Unfortunately, you have gone a little wrong here. The Blades are correctly stamped 9-12153.13 on their base. They are listed for the Fw190A-B with BMW 801C/D engine. The 9-12153.13 blades are specifically for use with additional balance weights that fasten on near the blade roots and reduce the load on the pitch change mechanism. When built as a complete propeller unit or "GERAT" this would be the 9-12153B assembly, as stencilled on Tom's blade, although that stencilled number refers to the complete assembly.
Also, similar blades that are not made for the weights are listed as the 9-12153.10 and they are used in a complete assembly that is the 9-12153A.
These two types of propeller Gerat (A or B) can be used on the same listed Fw190A-B with BMW 801C/D engine, according to the VDM data.
Cheers
