Looks like it could be an MXL type: (miniature extra light)
The number printed on your belt is probably an in-house part number for Emco use only.
You would want to look up a generic part number. For example, if your belt has 75 teeth and is 3/8" width (0.375 inch)
the part number would be 75MXL037
Thanks for your help, its very appreciated. I'll see what I can find using those parts numbers.OK. The original then, would be a 74MXL050 and you could probably use a 75MXL050 also
Shouldn't be too difficult to find
