There was a photo that I saw on the old Photopic site showing the underframes and bogies hanging around the back of Inchicore in about 1975, but they may not have survived for much longer after that.
That's because Flickr insists on cramming in as many photos per "page" as possible. Sometimes as many as 500 at a time. Not fun to wait for if they're all mega-high resolution....
I think there's only one BEMO HOm engine that sells for under £200. Everything else they make is some way over the £200 mark.
Even the very few RhB steam outline models they occasionally make retail for £300+ .....I should know; I made the mistake of shelling out for one. I was living on baked beans for months afterwards.
The ones I looked at appeared to be very black. As black as a priest's socks (which should be really black, and not actually just a very very very very very very very very very very dark blue).
