Hongwell Toys Limited are based in Hong Kong and specialise in die cast cars, their trading name being Cararama. There doesn’t really appear to be much of a web presence although there are a number of collector websites and sellers. As far as the twingo model is concerned, the two scales available appear to be identical in features, specificially the full glass roof.
There appear to be at least six 1:72 scale available, so that’s three more for me to look out for! More details of those at HongwellCollector.co.uk
I currently have around 120 twingo models listed. Check out my Twingo Object List for more details of my collection. Still lots to add though!
