Regarding shipping from England and the EU during these covid days...
As far as I've been told by several European sellers, even a small part,
like an oiler cap, could cost many times the purchase price to ship.
If I could get little parts shipped from Europe for a reasonable price,
I'd be happier than a kid in a candy store. I have had 3 engines shipped
from Germany, and I willingly paid the expensive shipping for them because
the purchase price was quite a bit more than the shipping price. The total,
to-my-door price, was within reason.
Good Luck and happy steaming,
Wayne
