FANTASTIC ANTIQUE BROADHURST CLARKSON BRASS 4 INCH REFRACTING TELESCOPE, THISBEAUTIFUL INSTRUMENT IS CONSTRUCTED OF BRASS, THE MAIN BODY/TUBE HAS A BLACK COATING AND IS FITTED WITH A RACK AND PINION TYPE FOCUSINGMECHANISM, FURTHER FOCUS ADJUSTMENT IS OBTAINED BY THE EYEPIECE TUBE EXTENSION,THE ACHROMATIC OBJECTIVE LENS IS HOUSED IN A REMOVABLE BRASS CELL. NOTEABLE WITH THE LENS HOUSING IS THAT IT HAS ADJUSTMENT FOR LENS PITCH WHICH IS DONE WITH THREE EQUALLY SPACED SCREWS. AT THE OTHER END OF THE SCOPE IS THE BRASS EYEPIECE EXTENSION HOUSING WITH THE ENGRAVED DESIGNATION: “BROADHURST CLARKSON &Co., 63 FARRINGDON Rd., LONDON, E.C. THE TELESCOPE IS CONFIGURED AS AN ASTRONOMICAL REFRACTOR BUT ON THE TUBE BODY THERE IS A MILITARY “CROWS FOOT” MARK SO POSSIBLY COMMISIONED BY THE ARMY? THE FIELD TRIPOD WOULD SUGGEST THAT! IT IS HUGE AND VERY SOLIDLY CONSTRUCTED WITH THREE LONG MAHOGONY LEGS, EACH WITH A BRASS POINTED END CAP. A VERY HEAVY STEEL FORK SITS ATOP THE TRIPOD ON A HEAVY BRASS SWIVEL YOKE, ALLOWING FOR SMOOTH 360 DEGREE HORIZONTAL MOVEMENT AND VERTICAL MOTION.

THIS HUGE TELESCOPE IS BEAUTIFUL TO BEHOLD AND IS IN FULLWORKING ORDER. THE OBJECTIVE LENS IS BRIGHT AND CLEAR GIVING QUITE STUNNINGVIEWS OF THE NIGHT SKY.

THE BLACK COATING HAS PROBABLY BEEN TOUCHED UP OR REDONE OVER THE PAST HUNDRED YEARS OR SO BUT IT STILL LOOKS GREAT. THE OBJECTIVE LENS APPEARS TO BE INSUPER FINE CONDITION WITH NO APARENT ABRASSIONS, CHIPS OR CRACKS, IT LOOKSCLEAN, FOG FREE AND BRIGHT, THE OBSERVATIONS I HAD BEING TESTAMENT TO THAT. THE FOCUSING MECHANISM WORKS FINE AND IS REASONABLY SMOOTHTO OPERATE.THE BLACK FORK MOUNT HAS ADJUSTABLE BRASS BARS WITH TENSIONERSWHICH WORK VERY WELL WHEN KEEPING THE TELESCOPE TIGHT AND STEADY WHEN FOCUSINGETC., THE FORK MOUNT PROVIDES FOR SMOOTH HORIZONTAL AND VERTICAL MOVEMENT OFTHE SCOPE.
