Amazing find...a secretly hidden car unknown to most then! Your chromed parts are absolutely correct for a British (ie Export) Standard model: hubcaps, bumpers, front and rear hood handles and door handles must be chromed too.
My only comments would be no stone guards as you mentioned, certainly no trim on the edge of the running boards and you should only have one polished metal (not painted as in Germany) front horn grille on front passenger-side fender. The white waistline is an optional add-on and I am still to this day not sure if it was automatically painted on originally. Of course, I am sure you'll replace the two front missing bumper overriders.
If you want to be 100% accurate, then the wheel colour schem should be: outer rim in L225 Jupiter Grey, inner rim in L87 Pearl White and black VW logos painted on your chrome hubcaps.
Value-wise, it's difficult to say...Even though Standards are by far rarer than Deluxe models in general, having a RHD makes it even more special. The problem is that most people don't understand this so as far as the market goes, it will probably be priced as any good RHD Deluxe Oval would be. The market and trends in price certainly don't reflect or highlight the actual rarity of some models. It's more about what's mostly in demand, so since a lot of people haven't got the Standard thing yet, I wouldn't expect huge excitement. Show them any old deluxe split of which there'll be dozens at a vintage show and they'll appreciate them more because ii's 'older'. I certainly don't always go by the motto 'older is better and rarer' but then again, I upset quite a few people with my theory so maybe I should keep quiet... Anyway, yes, your car is rare and the most important thing is that you know this, regardless of trends and fashion. A very very good purchase, well done!:d
