Serial Number History for All Floor Looms

print

We’re happy to help you with any problems you may have with your Schacht equipment. Before you contact us, verify the type of loom and have the serial number ready. Especially for older equipment, we can’t effectively help you without this information. Some very early looms were not assigned serial numbers. If your loom was built prior to about mid-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 tables 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, to the left. 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).

4Now-4Later Looms are numbered in the 4- series.
