Year of bars

[Clasec]

I'm going to use these bars on display saws and was seeing if someone would know what years they would have been installed originally.                                                                                                                                                                                                                                                                           16 in bars by CLASEC, on Flickr                                                                                                                                                                                                                                                                                              16 in. bars by CLASEC, on Flickr

The PT16381-B2 1976
The GW1416-50. 1976 or earlier. They didn’t use revisions on earlier bars, so there is no way of knowing exact dates.

Those are beautiful. I bought a new Power Tip similar to that one in about 1969 or 70. My XL-500 came with one like the hard nose in 1966.
