Numbers as a Guide to Date Bill Kibby-Johnson, Piano History Centre 271 Southtown Road, Great Yarmouth, Norfolk, NR31 0JB (UK) Tel. 3 bill@pianogen.org NUMBERS AS A GUIDE TO DATE by Bill Kibby-Johnson MIMIT In many of the items in our files, the american use of the hash sign or sharp (#) has been adopted (rather than the italian 'No.' ) to denote numbers, especially serial numbers: Also, in order to make long numbers easier to read, several readers have asked me to insert commas after the thousands, although these do not normally appear on the pianos. Hallmarks for silver and porcelain, etc.

Are published widely in many books, but the same kind of information is not available for pianos, and if there are no datemarks, serial numbers are one option, but dating pianos by their serial numbers is notoriously unreliable, partly because so much misleading information has been published. Datemarks are a much more accurate and reliable guide to the age of an instrument. Dating a piano by its number depends on four things: 1. The piano must have a number! Sometimes, it is so well hidden that you may not find it. (If you do find just one, don't assume that it is necessarily the right one.) 2. The numbers must be published.

Monington & Weston Art Deco baby grand piano, in a walnut case. Made in 1937 according to its serial number. Monington & Weston are perhaps one of the most.

Many are simply not available, although my files include many dates of numbers which are not published anywhere else. Books which give number dates include Michel's Piano Atlas, (which later became the Pierce Piano Atlas) The Europe Piano Atlas, and the Musicians' Piano Atlas and its supplement, for which I supplied appendices with action & key numbers etc. I am grateful to the Castle Museum, York, for copies of a list of piano serial number dates compiled by Mr D.R.

Homan, a piano tuner from Scunthorpe. Most of these lists end around 1935-6, so we imagine that they were collected around that time. Some agree with other published numbers, some do not, which brings me to. The published numbers must be CORRECT! A few years before I became involved with pianos, N.E. Michel published the first 'Piano Atlas' of serial numbers: Some of the numbers he published are wrong or misleading: Early numbers for Bluthner, Bord, and Brinsmead, do not correspond with the instruments.

Neither do Bristol pianos, which he wrongly attributes to Duck, Son & Pinker. Clementi and Collard dates are a complete nonsense. The Erard entries make no allowance for the fact that many instruments from London bear a separate sequence of numbers. Monington's numbers only show one of the two sets. Wornum's numbers are misleading because they do not give the Piccolo Pianoforte numbers.

These and other mistakes have been perpetuated by other books reprinting them without evidence to support the information, but then it is a difficult trap to avoid, and everyone quotes published information sometimes, taking it on trust. The Musicians' Piano Atlas published revised entries for Jarrett & Goudge, based on nothing more than my vague suggestion that Michel's numbers were about forty years out!

There are often different numbers on the casework, keys, wrestplank, soundboard, iron frame, and action: Which is the correct number? NUMBERS: Which is which? Some people solve this problem simply by choosing the number which best suits their purposes, or makes the piano oldest!

Often, the serial number may be imprinted into the wood of the casework, and sometimes it may be conveniently located on the top edge of the end of an upright piano, but this is by no means reliable, and grand case numbers are often harder to find, being hidden or underneath: Remember too the dangers of crawling underneath a grand - check that the legs are safe first. By the late 1800s, removable case parts were often imprinted with the last 3 digits of the case number, so that the parts could be kept together during manufacture, and this helps to confirm which is the case number. Steinways marked even the tiniest pieces of moulding in this way. Coincidences can happen, and a 3-figure model number may happen to coincide with the last 3 digits of the case number, as it did on an old Collard square piano I owned. Download film genji. Pleyel pianos of the 1840s would have the case number on the case, action, keyblocks, and various other places, and their published numbers seem about right. Having said all that, case numbers are not necessarily the published serial numbers, which may be painted onto the iron frame, or imprinted on the soundboard. Some of these belly numbers (such as those of Bechstein) run in separate sequences for uprights and grands, and exist in addition to the main series.

Ge concord express installer code. It cannot be done with the Fixed Display keypad. To use it, power the system down, then short the solder points - power the system up with the short in place for 10-20 seconds. If it does, you will need to completely reprogram the system - this requires a 2x16 or better Alpha keypad. I would imagine this only resets the User programming, but I have not yet confirmed this.
