Hi, Arthur told me he was having some problems with email over the past few weeks, so I checked with him last night, and he was not aware of your enquiry. He asked me to pass on his current (temporary?) email address to you, so I have PMed you with it.
P.S. I am not sure why, but Funk cannot upgrade RB250/RB202 to FXR, only the RB300/303 upwards.
