Spelling it "Kruger" may help you find more info, found this online http://horsegossip.proboards.com/thread/103734/kruger-saddles. When individual saddleries have saddles made they are often something like an Ideal rebadged or they're fully custom made. Like all M2M it can be a risk, more so than buying off the peg when you have a lot of consumer law behind you which doesn't apply to anything customised.
Thanks for link and the correct spelling of it. Well I have 2 saddles that don't fit one was bought of peg the other customed made that goes over last rib but otherwise fits like a glove. Kim lives locally to me so she can come check saddle say every 6 months as my mare is still growing and changing shape. She sounds like she knows her stuff, she's on the master saddler list. I have seen a couple of kruger saddles for sale but not many and they look really nice x
