There's plenty of Sepia toners available but Ornano was a small company and you need to tell us what type it was, presumablt A Bromide/Ferricyanide bleach followed by a wash then redevelopmeny in either as Sulphide or Thiourea toner.

There can be quite a variance in image colour depending on the exact formula so you need to experiment, As toners are the easiest of all to make up yourself I'd suggest going down this route.
