I was looking for a ship to pass as the 600 d-ton science vessel I'm creating for our upcoming Mongoose Traveller game, and I was simply not having any luck. Either I didn't like the layout, or it didn't meet the requirements of a science vessel.
Should have known, of course, that the Wayback Machine would come through. I found a lab ship variant of the Orca from an old site for a (now-defunct?) Zaon RPG, (warning: slow load) and I think it just might work. I still need to make a few adjustments, and I still have a little time to switch in case I find anything better out there.
(It looks like here the designer of the original ship plans is claiming copyright on the plans. I guess I'll need to PM him, though since it's for non-commercial use, it should be fine).
