Health warning: do not spend too long on the AMF87 site. Also, I recommend a look at Pierre Dominique -- at the other end of the scale really, they are a big 'box-shifter', but the stuff at the back of their storeroom seems to go back 50 years ... so another health warning there. The search filters are really annoying but you may start to find things emerge after a bit.

For German stuff (say you decide to put the old nose back on the V200) then the key source of detailing bits in German H0 is Weinert Modellbau and their catalogue is here.

Modellbahnshop Lippe (another box-shifter with an astonishing range) stock a lot of their stuff and so does Weinert Bauteile.

These are obviously suppliers inside the EU. I think we're clear that there aren't tariffs on toy trains etc (are we, BoJo?) so the real game is the postage. There is not a lot you can do about this but always add it to the cost of the bits you are looking at as you go. Reckon on spending from 10 to 20 Euro on postage. The specialists are usually the most expensive for all the usual reasons. I had a brief and fruitless correspondence with one of the suppliers above on this topic ;-)
