Deffo not Redlijne nor Tange, I'd have a guess at Akisu or just plain old generic steel not cro-mo forks. Welding and end caps are the first sign, and if Tange dropouts would not have washer tabs on them and Redline didn't do round holes, they were a solid dropout or early ones had a Patterson style cut out
. Have a look for a marking just above the crown race, might say something line 22.2 and Hi-Ten
.
