I understand what you're trying to pull off. There are different approaches to this.
Getting the ID is easy if you follow NoFear's method to dupe inventory items.
Once you get the ID, you can apply it to anything you want. I put up a guide for inbox since it's so easy to navigate to ID through it.
In the video I took the ID from an electronic circuit a member here already found, since that set of addresses is unique. Even if you didn't have those painting schematics, it's possible to navigate through the nearby addresses to see if you find items of the same type.
You seem to know what you are doing, that's why I'm just giving hints. If you're still having trouble I can try to make a video.
Mate, please. this video has already been posted specifically for your item and with the cooperation of many members for the ID and ways to achieve this.
