597mm tires have largely disappeared from new production. The two options I know of are Kenda K23 tires at 37-597 (marketed for Schwinn three speed bikes) and RJT 32-597. The Kenda is closer to a 1-3/8 width tire and the RJT is closer to a true 1-1/4 club tire. The Kenda is available widely online; I usually get mine from the Bikesmiths shop. The RJT, so far as I know, is only available from SJS Cycles in England. Then there are vintage tires, but it's a gamble to try to use old tires.
Haven’t seen your Lenton for a time. Nice machine. Ride before the snow blows mister. Good work.😊
Thanks 👍
