I recently contacted Revolution with questions about postage for three sets of Alcan PCA tanks on order. I received a helpful response within a couple of days which I think is a very acceptable response time given this is a small company with a handful of staff who must be extra busy right now sending out new stock. Also, it turns out I could have found the answer myself had I remembered to check https://revolutiontrains.com/faqs/ …this should have been my first port of call! Looking forward to those PCAs 😁
