I am looking for a soft copy of of a commentary on the रामचरितमानस, called रामायण परिचर्या, written by स्वामी देवतीर्थ, also called काष्ठजिह्व स्वामी. 

There is also a supplementary text to this, called रामायणपरिचर्या परिशिष्टप्रकाश.

Would be grateful if anyone can point me to a PDF of the said texts, or any other literature of  काष्ठजिह्व स्वामी.

Kind regards
