Schacht released the Standard Floor Loom in 1978; it's gone through some changes since then. The Wolf family started with the Baby Wolf in 1982, followed by the Mighty Wolf in 1985, the original Wolf Pup in 2000, the Wolf Pup LT in 2010, and the Wolf Pup 8.10 in 2016.
The serial number of your loom can help you determine its age. Some very early looms were not assigned serial numbers. If your loom was built prior to 1979, it is possible that it does not have a serial number.
- Serial numbers are pressed into the wood and can be hard to see. Hold a flashlight to one side of the castle or cross brace and shine it across, not directly on, the numbers.
- Through September 1987, serial numbers were sequential. You'll find lists below matching serial numbers to the year a loom was built.
- After September 1987, serial numbers indicate the date of assembly as MMDDYY, the type of loom, (for some looms) other characteristics indicated below, and where the loom fitted in that day's building sequence. Examples:
122214-WPLT-1 = 1st Wolf Pup LT assembled on December 22, 2014.
082818-FL8-LC-2 = 2nd Standard Floor Loom assembled on August 28, 2018, with 8 shafts and a low castle.
Wolf Looms
Wolf Pup and Wolf Pup LT: The serial number can be found on the top side of the cross brace underneath the shafts, on the right side of the loom. The serial number is the date of assembly (mmddyy.)
Wolf Pup 8.10: The serial number can be found underneath the Schacht logo on the cross brace under the shafts at the front of the loom. The serial number is the date of assembly (mmddyy.)
Baby Wolf: The serial number can be found underneath the Schacht logo on the cross brace under the shafts at the front of the loom. On older looms, the serial number may be on the castle side; if you added a high castle tray, you may need to remove the tray to find the serial number.
After September 1987, the serial number is the date of assembly (mmddyy.)
