An early, Gents' Pulsynetic WT, in a rather sorry state, has turned up on eBay. The pictures are almost as poor as the condition of the early movement. I have enlarged them considerably and played with contrast and gamma for posting here.
The armature impulse hook is pre-roller suggesting a very early example of the small WT. Certainly pre-WW2 and perhaps even 1920s. The black, cotton (or silk) wrapped, insulated copper wire on the electromagnet bobbins is early too. (Though the wire insulating wrapping may have been dyed green originally) The relay electromagnet's bearing plate is diagonal and has chamfered ends. (though not easy to see here)
The original black (semi-matt) paint on the mainframe is an early indication. As is the rounded "knee" to the cast main frame above the drive electromagnets. The contact assembly support post is oval, fixed and horizontal in the major axis. Even slightly later iterations of the WT have a slotted support base and a taller vertical axis with radiused ends. All these details point to confirmation of its authenticity as a very early C40A WT movement.
Sadly the movement is still too distant to make out any real detail in the auction images. Enlarging even the original images just makes them fuzzy.
It looks as if the gathering pawl is absent but I can't be absolutely sure. It may still be attached to the pendulum top. Though it looks considerably slimmer than on later models.
It looks as if all the bevel gear cluster is missing at the rear. The usual casting to support the bevel wheels is present but there are no bevel wheels present. Nor their stub axle block. Not in any of these images. Though the wormwheel shaft must be present because a leading-off coupling is visible at the left of the movement. So at least you have a drive to one or two dials.
The worm could be badly rusted but it is impossible to see such fine detail from these images.The Hipp toggle and contacts are thankfully present. As is the WT relay coil and mechanism. The wiring almost certainly needs sympathetic replacement. It should run happily on 20 Volts DC when it is finally restored. You will also need a master clock, of course. These WT movements don't keep time (at all) without a master clock to give a correcting impulse at half minute intervals.
Plenty of motion work here! Leading-off rods and contrate gears. (A simpler form of bevel gear) The four sets of motion work have minute hand counterbalance weights. Condition mainly rusty and corroded. Most of it looks as if it has all been standing in the rain for years!
The pendulum impulse coil bobbins look as if they have disintegrated. This requires real skill and patience to fix properly. Because it probably means making completely new bobbins and a complete coil rewind. If you want to retain any semblance of originality you can't just rewind the coils with new enamelled copper wire. It will look completely incongruous! Greatly reducing the value of the movement. The coils will be by far the most difficult part of the restoration. Probably requiring a decent lathe at the very least. It may be just possible to glue turned new bobbin ends to the original cores without disturbing the windings. Though it would require considerable luck and skill.
Another view showing partially dismantled movement and all the dial work. One dial hour pipe (in the foreground) is rusted right away! As it came from a stately home the turret clock system may have been abandoned at some point in its history. It could be somewhere around 90-years old by now.
As so few of these WT movements come up on eBay it is very tempting to bid with your heart instead of your head. You may be desperately hoping the poor condition means it will be more affordable. I would suggest that, unless you have the proper skills, or know a man who does, you leave this one well alone. It would be better to save up and buy one in much better condition. Knowing what is involved I would hesitate to take this one on myself.
I hope the auction winner has the skills to sympathetically return this movement to its former glory. It is almost certainly the earliest WT I have seen in this size. If its installation history can be confirmed it will almost certainly add to the pleasure of ownership.
The auction ended on £1420 GBP.
