It's difficult to make out the shape from the image provided. It would help to get a clearer image.

Other characters in Table 2.B of the evidence are shown as below. They are once common used, but I can not find the actual using cases for the submitted character.

U+25AB3 𥪳 U+7AD3 竓
U+25A58 𥩘 U+7AF0 竰
U+25A7B 𥩻 U+7AD5 竕
U+7AD4 竔
U+41C6 䇆 U+7ACD 竍
U+41C9 䇉 U+7AE1 竡
U+25A95 𥪕 U+7ACF 竏

In this case, 立突 are two characters for one French loan word litre. 立 corresponds to li-, 突 corresponds to -tre. This must be a typo. Metre should be 米突, not ⿰米突.

It is better to withdraw this character.
