Help! Missing part...

A collection recently was purchased, mostly PFM engines and a few from Tenshodo.  One of the pieces is a fine rendition of the Great Northern N-3 2-8-8-0, unpainted, from Tenshodo.  However, the model is missing the pilot assembly from the front of the engine.  If anyone can provide a replacement, or direct me to one, I would be grateful, enough that I would be happy to provide a 'finder's fee' in the form of a discount on a future purchase.  Feel free to email me at your convenience and thanks for taking  a few seconds to consider this.
