John Saggs and indeed Steve very kindly contributed to my site many years ago. It is still available on the'wayback' machine. John did indeed produce a range under the name UNICORN - I though I had a list on the site, but do have a copy which I will dig out. In the meantime if you go to the link 'Santa Rosa'www.shipmodels.pwp.blueyonder.co.uk you will get John's essay. The site was started in the days of dial up with limited skill and some of the links are now decidely dodgey and the photographs do not seem to be picked up on the site.
