Hi John
Thanks for contacting the Answer Army to post your questions.
The Original 36 unit's came with the HL-258-66 and H38-66. It was later that the HL-180-56 Bar became standard with this Unit that is also known as a Husqvarna 136. I hope this information will be helpful.
Thanks again from the Husqvarna Technical Services Team
