Long time since I posted here! You know, I know Dave Taylor fairly well and he and I discussed this one on the phone before he offered it for sale ( he knew my interest in the S.C.) I told Dave i would research Tolles a bit more and found that he was listed in Boston only in the post-war years. You are absolutely correct. Dave is a great guy with a lot of integrity and has wonderful items - but this is definitely post war. I am curious about the last comment you made- can you email me privately?
BTW, I just got what i hope is the real thing - a James Queen manufactured telescope marked USA Signal Corps - did you see it on ebay? PLease PM me...
Happy New Year, by the way!!
