Erik,
I have engaged with Jefflit above but he is yet to determine if he has the "rubber plug" portion.
Therefore, regarding your kind offer to check we should wait on an outcome from jefflit, so I dont waste your time.
I will let you know, clearly it would make sense to ship direct to me.
If we do approach your contact it may be easier to introduce me direct to the gent with the parts to save you the trouble..
My wife speaks german so I can employ her to help me!!!
Thanks again,
Mike
