Trying 2 find out name of interior color/ restoration Eureka 3712B

[vac_master_g]

Trying 2 find out the name of the interior color of my Eureka 3712B canister. EurekaPrince says the machine is referred as Sweet sixteen. My first vacuum Eureka 3712B, came from my cities recycle - excellent condition, no attachments though; just bought another, the same model from someone on an online auction site. The interior where the dirtbag and motor are located is covered in rust. However, it has all the original attachments.
Any suggestions on an alternative color that is close to the original? Any suggestions of sellers that offer Eureka factory paints?
This picture is of the interior of my first machine.
Thanks
