That is exactly why I was asking, Its badged 048 and the fuel and oil caps are both on the handle side of the motor. I was expecting it to be 1117xxxxxx from what I have been reading. Is it an 048 if it starts with 1127?? or is the 1117 just for parts numbers??
My 048's serial number is 111026752 and it looks like this. Does your saw look similar/the same? The 042/8 is the only Stihl I can think of with both the fuel and oil caps in the same location, so I'm guessing your's is one of those two. What exactly do you want to know?
I know nothing about saws. I just picked this up to cut off stumps, and was doing some researching and sounds like it is some what of rare saw.
I was expecting the serial number to start with 1117 from the info in this thread, just making sure its not just a bunch of parts thrown together to make a saw.
