Science & Medicine Antiques

The two larger pieces are unmarked but there’s a number 2 on the mirror and 30 on the other piece. Of the 4 other smaller pieces, one is unmarked and the 3 others are stamped 19, 50 and 80.

Used but not abused and well protected in its cosy little leather-bound box - stamped E Leitz Wetzlar, 2 and Ocular Ehrlich (I think). An interesting piece.

The main part of the body tube has a threaded insert that will not support an objective. The extra lenses to be seen in the photo do not fit the stand and have a very, very small thread. There is a nice signature on the Limb.

The artist sees both scene and drawing surface simultaneously, as in a photographic double exposure. This allows the artist to duplicate key points of the scene on the drawing surface, thus aiding in the accurate rendering of perspective.

A great looking antique WW1 military marching compass by J. Wardale & Co, fully marked, dated and numbered (see photos), in a good antique working condition (signs of age and use).

TROUGHTON & SIMMS SCIENTIFIC RULE. TROUGHTON & SIMMS, LONDON.

It has two Objectives with the small older thread to society adapter.

This is a very old and unusual boxwood scale, I believe is a Gunter's One Foot Scale Rule. I sold a similar one a year ago. I trust you experts know what it is. Scales marked on the front: Cho, Rum, Sin, Tan, S.T?.

14 bone (?).

A RELLY NICE WATSON & SONS BRASS MICROSCOPE OBJECTIVE LENS 1/6" 0.87 N.A. WITH CANISTER.

They stand 5.5" tall.

In June 1, 1912 catalog #3090. M.E. Crowell Electrical Apparatus for Schools. Patent May 10, 1898.

A FINE MAHOGANY CASED MONOCULAR MICROSCOPE BY "SMITH & BECK" Circa 1860.

IT IS IN ITS ORIGINAL LEATHER CASE WITH THE INSTRUCTIONS. WE ARE UNABLE TO TEST IT BUT IT LOOKS AS IF IT HAS BEEN WELL LOOKED AFTER. SOLD AS A COLLECTORS ITEM.

All in very good condition, allowing for a little wear around the brass eyepiece, with no splits to the mahogany and generally the brass work presentable and tidy, with the draw function working well and not floppy.

A very fine Georgian Zograscope. Dating to circa 1800 and of very good quality. The height of it is 70cm. With very nice inlaid decoration.

This surveyor / Gunter chain is in untouched 'as found' condition. This is a fine and highly collectable early land surveyor’s chain. The condition is great. 1 chain by 10 chains = 1 acre. One mile = 80 chains.

The jar has four sides and a round fluted neck and base. The lid is conical/pointed. Both the lid and jar are in great condition. The jar stands about 13" tall with the lid.

WEIGHING 80G. NICE QUALITY WORK. CIRCA 1850.

Buckle is marked “Homa, SWISS MADE” no keys included. but it’s all together! Feels stiff to open. Could b e displayed as is.

Probably military. Made for the United States and United Kingdom market (cardinal points wrote in english). Excellent condition - near mint (both mirrors).

IT IS 6 1/2", AND IS GOOD OLD USED CONDITOION. EACH ITEM IS SOLD IN AS IS FOUND, USED CONDITION UNLESS OTHERWISE NOTED.

Age guess circa 1900.

Not sure if sterling silver or not. Do not see any marks. 2 small dark marks in corner of the nose bridge.

Original blood lettering tool, with 2 blades folding into brass handle, length 10cm. Worldwide - £9.00.

Antique Victorian Drafting Set. Made by AG Thornton Ltd, Manchester (England). Two of the tools have either bone (or iv.) handles. The ruler/scale is bakelite ( an early form of plastic). I am sure that not all of the tools are original to the set, but at least 7 are marked "Thornton".

They are glass and marked Standard Twaddels Temp 60 London. Four of them are marked 3 4 5 and 6 which look to be part of the original set. Two which I do not believe are part of the original set are marked 1 and 2.

The position on the body in which the cupping glasses were to be applied was connected to the disease it was attempting to cure. They could be placed anywhere from head to toe. The air in the glass was exhausted by burning a candle and the vacuum created in the glass caused the skin to be sucked into the glass on application.

Double rack chromatrope in wood and brass intended for a magic lantern. It has a brass housing which holds two handpainted glass disks. When the crank is turned the disks rotate in opposite directions producing an effect similar to that of a kaleidoscope.

Only because this is a very old antique electric appliance, I am adding sold as-is/ as found/ as seen. (I'll list the other motor next). I plugged this in and it runs super nicely. Very smooth and quiet; no squawking noise; didn't have any incorrect vibration!

They expand on a floating spring system so should fit all and they have good strong magnifying lenses fitted. They are in very nice original pre-owned condition, ideal for use and as photos show still display very nicely.
