This is a Simington451.
The chain is Oregon 75CJ.
Any .375" or 3/8", .325" or. 404" pitch chisel cutter chain can be used but angles will be different depending on size and brand.
The stone is a Madsens Blue Alumina oxide or 'ceramic' stone.
Yes, we are well aware of the subpar camera work/angles. This will get better with time! We appreciate the patience and any questions you've got.
Thank you
