Having picked up the Ruined Factorum sprue that came with Warhammer 40000 Imperium 31 a couple of weeks back, I set myself a reminder for today, to purchase issue 34 for the second sprue .
The ruins are from the The Battlezone: Manufactorum – Sub-cloister and Storage Fane kit which did cost £37.50 at Games Workshop and contains two similar sprues. So at £8.99 you would be making a saving of £9.76. However you can’t buy the kit anymore anyhow.
This time, as before, you get two more corner ruins, all coming on a single sprue.
The final models, combining the ruins from issues 31 and 34 (did) look like this on the Games Workshop website.
Another view.
