It's not a bad starting price but not strictly correct for a K0 although it will fiot fine. Should be either double slash cut (late '69 to early 70) or rear single slash cut .. later 1970. It's more like a K1 early K2 type. Shows how prices hiked, I bought one new (Gen. Honda not NOS) in 2008 from DSS for 79 quid and sold it in 2011 for 210 GBP. DSS had to go though their stock of 14 to find me one with perfect chroming !
