1927/8 B&L 4" maybe F12 but I don't remember the ratio for sure, white paint on solid brass tube but thick, not a  shell. OTA is 35 lb. I think.  I'll check if that doesn't sound right. Impressive optics.

I have what I think is an early Zeiss traveling scope that is brass.  However, I am not sure if it is a traveling model as it is a longer focal length then the Zeiss traveler I do have.  

Please, Post a pic of you can!

Here's my 1871 Clark 4".

 

Oddly enough, 3 of us in the greater Boston area own 1871 4" Clark scopes, and they are all different! Tube diameters are all the same, but finder ring spacing varies, lens cells vary a lot (3 vs 4 screws, 2 are inside tube, 1 outside).  So even within just 1 year there were significant changes.

That's awesome Peter! A real Clark made by Clark hands!

Are you saying that you have a Zeiss Reisefernrohr with A objective???? shocked.gif  Those are rare as hen's teeth.

Please also take a picture of the letters on the lens cell. A 60mm A objective should have a focal length of ~1050mm.

Ultra, ultra cool!  You may be the only human on planet earth currently observing with a speculum metal mirror.  How old is the scope?  Casting, grinding and figuring a speculum optic is on my bucket list.  I may be the only human with that on my bucket list!

 

funny you ask

I was out last night looking at moon

2.75 rb bate speculum metal Gregorian

Thomas Cooke and Sons LTD 4" refractor, circa 1897, set up at the Amateur Astronomers Association of New York's Autumn Starfest two years ago in Central Park's Sheep Meadow.  Scores of the general public looked through the Cooke that evening at the planet Saturn.  I was asked many times "Why does the image in this telescope look better than all the other telescopes here?".  Then I would tell them how old the telescope was, to their amazement.  Thank you H. Dennis Taylor!

I do not know what I was thinking.  They are both the same length.  Sorry.   I do not know why, but I remember having another Zeiss that was shorter.  Now I cannot find it.  Maybe my mind is on overloadundecided.gif

Wow, what an impressive collection of brass scopes!

Indeed!  I'll reiterate what a broad collection represented here!  I was expecting a lot of duplicate makers, but not so.

 

I have to say, when it comes to refractors, I LOVE brass refractors.  I bought a 100mm f/13 Vixen-spec objective to build a modern brass tribute/homage scope.  Five years ago someone here (can't remember who - he hasn't posted in a while) bought a 100mm Criterion achromat set and I suggested building a brass scope.  Shortly after the Vixen-spec became available (posted here in the ads thread as a full scope).  I bought everything but the tube.  Life has gotten in the way, but at some point I WILL build it.

 

Originally I was planning on building a homage to the Transit of Venus scope.  Now I'm not sure because that will involve more complexity that I originally envisioned.  I may build an homage mount to other older scopes (then again, when I get around to it, the Transit of Venus homage may simply call my name).  Like I said, I love brass refractors.  No reason not to build a modern version.  There are two manufacturers of brass refractors in the UK.  They are also modern homages.  Beautiful scopes.

Here are some photos of my 2 early B & L scopes both are of the same vintage from the 20's. I also have just acquired Dave Trott's 1927 Zeiss but don't have photos of it yet. All three of these are heavy brass scopes with most of the brass being painted, in the condition they will stay.

 

B & L 1928 60mm
B & L closeup 10
New photos Of working B & L 5
New photos Of working B & L 3
 
These are wonderful telescopes and give me much joy.
