Link to Rav Wolfson's Source

In the post yesterday, I noted that Rav Wolfson quoted "a Sefer from Rav Schlesinger from Monsey's grandfather".  That book happens to be She'al Lecha Ot, and it clearly designates 5775 as a Ketz date (see below).

I had forgotten about this source which Rav Fish mentioned over a year ago and I blogged at the time.  I subsequently added a reason #16 to "The 5775 Hope for Geula" post: 

• 16) She'al Lecha Ot

Rav Mordechai Schlesinger ZT"L wrote in She'al Lecha Ot (read the whole essay from pdf page 109 to 115, but especially p. 113) in the name of an old book that Yemot Hamashiah would last from the year 5600 until the year 5775, which is the real Ketz.
As Rav Fish brought down in 5773:

It's brought down in the book "She'al Lecha Ot" that he found in a very old book that the Keitz of Mashiah is hinted to in the verse (Shemot 38:28) וְאֶת-הָאֶלֶף וּשְׁבַע הַמֵּאוֹת, וַחֲמִשָּׁה וְשִׁבְעִים, עָשָׂה וָוִים, לָעַמּוּדִים [And of the thousand seven hundred seventy and five shekels he made hooks for the pillars]. The hint is:

ואת האלף - which is Rashei Teivot for ואם תמנה ה'אלף - and if you will count 5000
וּשְׁבַע מֵאוֹת וְשִׁבְעִים וְחָמֵשׁ - and 775
[Verse 25's version has the word] שקל - which is Rashei Teivot for שנת קץ לישראל - and year of the Keitz for Israel
This year should be a year of salvation - תְּשֻׁעָה - for Israel
