Yeoman JYA O&K

[The Fatadder]

While searching for some brass components in the workshop, I’ve come across a part built Intercity Models kit for an O&K JYA box.  This was one of my first attempts at a brass kit (and I didn’t know what I was doing) and there will be a lot to save it,  (For a start the side that’s built has all the ribs soldered to the wrong side!). However the biggest omission is the floor is missing.  There is a chance it lives on in a different scrap box, but more likely it will need a scratch built replacement. 
 

I’m hoping that someone who has made the kit can take a photo of the under side that I can work from.  As the instructions are long since lost, I will be relying on photos to build the rest.  But the chassis design is rather hard to make out
