D&S 213 Combine

I recently read the book "Rio Grande Narrow Guage Varnish", and will find it very useful in the future. On page 117 it talks about D&RG Combine 213 and how it was sold to the SG&N in 1899 and its disposition is unknown. Prior to reading this, I thought that the 213 combine on the D&SNG was an original D&RGW coach. So was the current 213 built by the D&S sometime within the last 20-30 years? If so why did the D&S specifically want a combine coach? I know that Today the D&S does utilize the separate compartment in it for some storage and some other things related to special events work but in our modern world why would you want to build a combine when you could just build a full passenger coach? Or did the D&S somehow get ahold of the original 213?
