Production commenced 1993. The date is not coded into the serial number. I use serial numbers in the form:

MMM-NNN

Where MMM is a 3-digit model identifier, and NNN is a serial number, starting at 1 for the first one built. Model numbers are as follows:

200 = Imperial

300 = Continental

325 = Continental Combo

400 = Galaxy

500 = Comet

600 = Meteor (series I)

700 = Meteor (series II)

Tone Lizard

"I started building in 1994.
I am located in Winnipeg, Manitoba, Canada.
The first dozen or so amplifiers I built had 'serial numbers' and a year handwritten inside the chassis. The panel will be black lettering silkscreened on a gray background. After that, there is absolutely no written serial number, date, or any other markings inside or outside the chassis. The only way to tell is by an experienced eye. The first dozen or so amplifiers all looked like a tweed Fender, but were covered in different colored vinyls. The next 'batch' of two-dozen or so looked like silver-face Fender combos, and could have been made by me up until 2000. The panel will be a laser-engraved plastic unit that looks like a Hi-Watt. The final batch a dozen or so were heads that looked like a Marshall, and were made up until 2005. This was done to have a cheaper selling price, and allow the customer to use his own speaker choices. The panel will be laser-engraved on a brass backing. Again, there will be no marking identifying a year or serial number. These amplifier were just made mostly 'on spec' (just to see if they would sell) and eventually sold through various local music stores or as a demo model through my web site. Whatever it took to get them sold. After the last one sold, I took a holiday that continues to this day."  [Source: Randy Jamz/Tone-Lizard Amplifiers, email 8/3/2008]

Torque

Torque, founded by Jim Edgeworth, began in retail shop in Darlington (UK) in the early seventies. Early amplifiers were made in small quantities for retail sale through the shop. A major UK national distributor commissioned a range of amplifiers under their own brand name to replace their existing range, which had been imported from the far east.

This first major contract initiated the formation of the limited company in 1978 and a move to a 2,000 sq. ft. 'starter workshop' on the Chilton industrial estate. Within a couple of years the company expanded to a 5,000 sq. ft. factory in Darlington, but with only one customer and product line the recession of the late 80s led the firm to expand to other electronics and to promote amps and products to other international markets. Factory expansion occurred again in 1990 and in May 2003 manufacturing moved to China. [Source: Grandm ]
