Their business started out doing around $2.5 - 3M annually in the beginning and peaked near $5M in the mid/late 90's.
Roughly 10% was European; 40% US and 50% Pacific Rim.

Thanks Eric300,

Your posting had me re-look at the sales quantity figures I used. They came from two sources. One was annual sales reports - but I didn't have these for every year. There was a "sales overview" report made up around '98 which I assume was used in negotiations dealing with the sale of the company. Their totals agreed with the other data I had. They continued to make product for another year or so after the sale. I found no sales data for that time period, so I simply extrapolated the few previous years data out for the company's remaining life. I feel pretty confident in the totals

It happens that I also have a few final test reports on certain of their product - each with a unit serial number. In particular, the P603 modules and the Seraphin speakers. What I found, especially with the 603 module, is that although they only made a few dozens of them, the serial numbers of them are all over the place - two, three and even 4 digits! I can only presume that a serial number on a particular product may NOT represent the actual consecutive total of that product built. I can understand how this situation may have come about. Cello never obsoleted a product. your Palette/Master supply is undoubtedly of late (in their 15 year) production; plus they were built in "batches". So it could have been a year or more since the last few were made - and perhaps by a different person or persons. Let's chalk the discrepancy up to incomplete record keeping.
