The chain was a old Stihl RSC made into RSL on a Silvey Swing Arm grinder. The chain was well used and so the cutters were shorter.

Someone had cut the rakers down too far before I acquired the three round chisel chains in a horse trade.

With the sharp square angles and the low rakers, the chain was almost too aggressive for 70cc chainsaws. A 90cc would have loved it?

There was no special modifications done on that chain such as tunnelling, stoning, or thinning, it is just a work chain.

But to use a chain like this compared with a new round ground chisel LGX or RSC chain makes you think you're cutting cheese instead of wood.

I have a couple more old Stihl 72DL ones just like it.

I had a 362xp.  Just never thought to compare back then or get pics inside etc. 

I saved those pics now though. Thanks.
