As Mick mentions in his remark, "to deem in good shape" is slightly old-fashioned although not, I believe, enough that you should not find out how to make use of the idiom. I would not contact it "Victorian" English, as it is a phrase that sees typical use even now. https://elliottjnrvx.blogchaat.com/36838989/clean-litter-practices-uae-an-overview
