Gāndhārī Ekottarikāgama-type sūtras
by Mark Allon, Andrew Glass, British Library
British Library Kharoṣṭhī fragments 12 and 14
Paraphrased from page 7:
The 'Budhabayana-sutra' appears to be part of a Gandhari (AD 10-30) version of the Anguttara Nikaya Section of Fours, but unlike the sutras which precede and follow this one in the recovered scrolls (corresponding to the Pali AN 4.36
and AN 4.14), it has as yet no known equivalent in Pali, Sanskrit, Tibetan, or Chinese translation. Later (p. 224, the first page of the link) the authors stress that because of this, any translation must be provisional.Here
