Nucro and Acro appear to be related as both have a similar address, similar packaging and both were distributed by Bradshaw Model Products. The bogies illustrated below were described as 0 but are almost certainly 00 rather than 0, as Nucro 00 bogies were supplied with a boss to hold a Peco coupling, for compatibility with Dublo and Trix models.
