A couple weeks ago I got a 400mm projection petzval off ebay for a very little. Dismantled it, cleaned it, and checked a design diagram to make sure I reassembled it properly. Thought I'd check the one I got from Richard...you know...just in case. I had elements reversed.
Anyway, here is one I made with it on 8X10 X-ray film...after fixing it.
