I actually have all unique and set items forwarded this way, although I don't play anymore I can see if I can find screenshots or readouts.
I wrote about this in this forum 6-7 years ago when I discovered it myself. What you need to do is convert a character with the items directly from pre-LOD (1.07) to 1.09 (or 1.10, don't remember). If you do convert a pre-LOD character to 1.07 first, then 1.09 (or 1.10 and higher) it will become 'normal'.
For instance, find a Gull dagger in 1.00 - 1.06 and convert that character directly to 1.13. The Gull will get 100% MF, even though it actually only has 50% MF. However, if you first convert it to 1.07, then 1.13 it will retain it's original 50% MF.
Edit:
Found Steel Clash with +1 sorc which is great in 1.13 classic and the Jang Bong staff with 100% ED (24-56 dmg) and 2 paladin skills (0 strength requirement and character level 1 requirement, easy twink!!!! :O )
