Were any of the early ILF bows non adjustable for weight or Tiller? I know the ones I see advertised now seem to all be. Thanks for any info.

All ILF bows are adjustable and always have been. The amount of adjustability depends on riser limb pad angles, retaining bolt length, limb butt thickness, which is standardized, but may be some home made versions around, limb composition, etc. Most of these features have become standardized as well.

there were some Hoyt risers that used ILF limbs with a different fixture that were not adjustable.  But ILF risers  are all adjustable to my knowledge.
