Outside hinge with 3 barrels: Many of the early hinges were replaced, as have been some later ones, so the hinge barrel count is not always absolutely accurate as it is possible a repair replacement has been made. The appearance wasn’t so great and there was a tendency to rust, so a black crackle paint was used on these lighters. Black crackle Zippos were apparently produced only for shipment to armed forces overseas and none were produced for domestic sales. The difference between a and Zippo can be determined by the insert as the ones had markings on them.

Introduction Conversion Converting dates in the calendar we use into Roman dates is tricky and involves some degree of compromise. The Roman calendar was altered many times as errors in previous calendars were corrected and political considerations led to compromises in those changes.

The initials of the potter who threw an original piece of pottery on the wheel. The initials of the person who adds or enhances detail on both cast pieces and pieces thrown on the wheel by others. The person who applies the glaze to the once-fired bisque pottery. To be fair, the artist who first created a design should be identified as the “artist” of a piece which subsequently gets cast thousands of times, and should have his initials incised on the bottom. But such is not the case.
Only on wheel-thrown original pieces is the actual artist identified, and only on those pieces is the mark called the “artist mark. This is done when the etcher refined a piece or added carved decoration to the thrower’s original. Without knowing whom is whom, it can get confusing. We hope these tables will help unravel the mystery.

Roman numeric system Basic decimal pattern The original pattern for Roman numerals used the symbols I, V. Each marker for 1 I added a unit value up to 5 V , and was then added to V to make the numbers from 6 to 9: This feature of Roman numerals is called subtractive notation.

In Roman abacus several grooves were carved into the board along which counters were moved up and down. One counter was laid in each of the upper grooves, while four in each of the lower grooves. Some additional counters were laid on the right to facilitate the calculation of fractions. The normal method of calculation in ancient Rome, as in Greece, was by moving counters on a smooth table. Originally pebbles calculi were used. Later, and in medieval Europe, jetons were manufactured.
Marked lines indicated units, fives, tens etc. This system of ‘counter casting’ continued into the late Roman empire and in medieval Europe, and persisted in limited use into the nineteenth century.

However, much controversy has been stirred in recent years due to the arrival on the market of a rather plentiful number of small coppers which, while in their entirety are missing the key part of the obverse legend needed to positively identify them, share in common several features which seem to leave no reasonable alternative.
