A few days ago I got the S&S Mod 601 (altaz mount) that was auctioned on Shopgoodwill. As I expected it was a fratricide war with other CN members... I paid a higher price (a few extra ten dollar bills, not a fortune!) than what normally a vintage 60x700 goes for, but I really wanted to pair it with my other early S&S 60x700 that optically has impressed me quite a lot: https://www.cloudyni...fe#entry7757942.
I defined this Mod. 601 as "early version" in the thread title because strdst has posted a different S&S 601 version, also on altaz mount, that I presume may be somewhat later :
I am currently away from home and have only the OTA with me, so I start with what I have. Later, info on the mount, accessories, JTII tag and a copy of the manual will be posted.
