'91 Kona Seat tube int' diameter?

[Wold Ranger]

Just taken delivery of a 91 DB HT Kona frame, Cindercone/lavadome/Firemountain model) previous owner not sure of int diameter, has captive forward facing clamp, mic's up between 26.1 and 26.5 but seems to be 26.4 in most places? Is this correct size? Post '95 were all 27.00

Yup, I have a '91 Cinder Cone, and 26.4 is the right size.
