Old.The last one would have been built in the early 80's. Is yours red or blue?

Here is a link that might be useful: Homelite

It is red. I have heard there is a UT number. The tag on mine has a lot number and serial number.

I looks somewhat like the one on the link. It does not have the hand guard or the nose tip protector.

That is a great saw. That along with an oregon bar and chain make an excellent combo. Early 80's I believe. Very light and powerful.
