I'm glad that Ipswich is all Mark3 and headspans so reasonably easy to scratchbuild. Ravensclyffe is Mk1 and portals, fortunately I've got just about everything I need for that layout with the winding down of N-brass making the etched portals no longer available. Hopefully someone will bring out a new range of Mk1 to take over from Nick's work, I am not convinced that laser cut or 3d printed will be strong enough for tensioned wire systems. I have no use for the new GWML type equipment but it's good that it may be becoming available to make modelling OLE of different styles possible, I wouldn't want to try to scratch build the GWML stuff!
As for the Peco portals, will we ever see them?
