1/200 trumpeter destroyer propeller

Harquebus

Are you talking about the black plastic 4 blade propellers that comes with Trumpeter Courageous, Harbin (Luhu) and Luda class?

I notice there are usually four propellers in each box so someone has some to spare. They measure approximately 17.6 mm. Is it possible to contact Trumpeter and purchase them as spare parts? I can order spare parts from Tamiya for a few dollars.
