Would anyone be kind enough to point me how I can procure digital or physical copy of the following work

Problems in Sanskrit Grammar by (latr) Pt Venkateshshastri Joshi

edited by Koparkar, D. G. and G. U. Thite,

Dastane Ramchandra & Co.,

Pune.

I tried to contact on the number of the publisher from google, but the number does not exist.

Thanks,
