As I read the second image above, the printed text version, it looks like 01460 is a typo for the character 拏 in 本拏哩迦 (puṇḍarika). So, it would be more helpful to see the full text of the entry 牽我 to the left.

This character is also used in 《碣石調·幽蘭》 which is the earliest 古琴文字譜, that means the variant of 牽. It is also one fingering letter name now. This is the last unencoded Han character in 《碣石調·幽蘭》, so it will be very useful to encode it. There are other unencoded punctuation in 《碣石調·幽蘭》.

It is a variant of 牽 according to the MOE variants dictionary (https://dict.variants.moe.edu.tw/variants/rbt/word_attribute.rbt?educode=A02498-009):

Re #9894:

Yes, Taisho Tripitaka misplaced this character and we do not have more complete evidence, but I hope Eiso Chan would provide additional ones if needed.
