i believe they were the oregon chain with triple chrome on the teeth. not sure what they were called, or even if they are still made. last one i bought was about 6 years ago

You are most likely referring to Oregon Multicut chain. You still have to sharpen it, can be done with file but a grinder is recommended.

 

Type 90 is 3/8"P pitch and 0.043" gauge which I am not aware Multicut chain is available in? You can get type 91 3/8"P pitch 0.050" gauge, which is M91VX.

hi would the type 91 chain fit the type 90 bar regards wukkie1

No........type 91 chain has a gauge of 0.050",

whereas type 90 has a gauge of 0.043".

 

So the groove in a type 90 bar is too narrow to accomodate the 0.050" drive links on the type 91 chain.

 

My brother recently bought the wrong chain and so prized-open the rails on the guide bar to accomodate the bigger chain...but he's a nutter.
