Hi mate,
I believe I had sold out of all the shrouds, however, can have others made. It isn't really economical to do 1 offs however, I used to do a minimum run of 10. Dasic' shroud is one from the very first run which were done in polished stainless. These weren't terribly cheap, I think they were circa $450 with fans at that stage. I generally don't supply the fans anymore and let the end user source them. They are designed for a spal 11 inch fan.
I can put an EOI up for a bit of a group buy, if I can sell 5 of a bunch of 10 I'll be happy to do an order. Lead time might be a few weeks at minimum as I have other things on the go right now and the shrouds need welding and finishing on my behalf after laser cutting and CNC pressing.
Nowadays I usually just fabricate in aluminium and can have powder coated if requested to colour of choice. Taking a guess of of previous runs I think the shrouds would run between $160 and 180, plus powder coating if required.
Anyway if you seriously interested I can put a post up in next few days and see if we can get anyone else on board.
I only have old photographs laying around of them, see below.
