Sinhala Kaccayana Grammar editions

Dear Eisel, Jim, Ole, etc,

In the library next door I just found an old 1895 printed Sinhala editon
of the Kaccaayana-sutta-paa.thaa by Jinaratanatissa thera (11 pages) and
a 1886 Kaccaayana-vyaakara.na edition by M. Gunaratana, revised by the
reknown scholar Hikkaduve Suma''ngala (135 pages). Are these of interest
to any of you? Bound together with these in the same leather cover are
also an edition of the Baalaavattaaraya (1901, Devamitta), Padasaadhana
(1887, Dhammaananda), and a Moggalaanaya-vyaakara.na (1899, Devamitta).
I noticed is that there seem to be quite a few copies, MSS as well as
printed editions, of the Padasaadhana, so it seems that it is or was a
popular grammar here alongside the Baalaavataaraya. The latter is still
studied in monastic schools by young monks but  I am not sure about the
Padasaadhana. I was told that the only part of the Kaccaayana still
studied is the Dhaatuma~njusa.
Best wishes,
