1880's Harbourmaster's telescope new
      #6339021 - 01/27/14 03:32 PM

I've come across a harbourmaster's brass refractor, reportedly from the 1880's. It does not have any identifying plaques or logos.
It is ± 4", ± f/10 or so, brass tube and dewshield, brass and wood alt-az mount/tripod, several eyepieces in individual focusing tubes. I'll post some pics once it is assembled.
How can I find out who made it and when?

there is a very good chance it was made in India quite recently (if so dont touch it) a Photo would tell more, Im just guessing based on the large number of fakes on ebay.

Post a picture or a link to one. Harbourmaster is the name of a well known series of faked antique telescopes from India, but there appears to have been scopes from well respected makers in the past to bear the same name. It's impossible for us to tell without a picture.


Clear skies!

By Harbourmaster, I mean it reportedly belonged to a harbour Master!
It is genuinely old, real patina on brass, real fungus on glass (as far as I can tell but in Durban's humidity who knows?). I'll sort some pics and clarify it's history. Hopefully not a fake.
Scope belongs to a friend, I won't be buying it :-)

I could well be wrong, but it seems to me that the brass on the tripod looks close-to new.....and the legs don't look 130-years beat up. here's a clue....are any of the screws phillips-head? If so, it's new. There is an active industry in India making repro optical instruments that are darn near (but not quite..) actual nice scopes.....

That looks "genuine." Most of the repros have helical focusers that look like plumbing fixtures. The lens cap appears stamped brass, rather than heavy machined brass with a ridiculous chain to hang it from the end of the tube.

The tripod also looks vintage, though someone polished the brass at some point (or it was hardly used).

looks too "new" condition wise to me not a chip or mark on the wood, all the metal bits look too bright, perhaps restored?

Ok, here are some pictures. First the objective lens - 93mm clear aperture, looks like a single piece but not sure.

Eyepiece collection, one appears to be a brass eyegaurd, one may be part of a finderscope. A couple are barlowed.

Focus drawtube, the knob appears to be a lockscrew, there is no focussing mechanism as such.

Lens cell, nicely implemented collimating setup, but looks like it was not recently collimated.
The alt-az mount is solid brass and beautifully damped. The tripod and mount look to be partially restored with the brass polished up.

You've convinced me, it's indeed an old scope! Is that a crack in the objective, or just a reflection? It's a truly nice treasure, whether restored for use, or just displayed!

It's a crack about halfway across the objective. The intention is to clean it up and see what it will do.

No way a repop is going to have a collimatable cell. The collection of ep's is telling too. Got to be the real deal.

That's a focus knob. These old scopes have an internal rack and pinion with the rack mounted sideways on the inside of the tube, so the pinion gear on the inside from the focus knob bears against it.

That cracked objective is a crying shame, but I wouldn't mess with it. It would be a doublet.

-Tim.
