GWR Wagon Chassis seen on S7 stand at Reading

[NewportRod]

I saw a GWR wagon chassis (or components thereof) on the S7 stand at Reading last week. It looked interesting and I made a mental note to return to enquire about it, but didn't get an opportunity. Would anyone like to fill me in in on what I missed please?

What you saw was a prototype nickel silver model of the GWR 16'0" underframe circa 1900, designed from drawings in the NRM, drawings in the GWR Engineering Society proceedings and measurements of wagons at GWS Didcot. Chris Brown is the master of this project - PM him at @ChrisBr .
