Wudstix, I had one just like yours (it was for sure a Howatt). Purchased in 1983 with 62# and 55# limbs. It had knurled thumb knobs for mounting the limbs to the riser so no tools were needed. In 1988 I got an itch to get a custom, and ordered a Bighorn by visiting their shop north of Denver. It was 63# and with the laminated riser it weighted a ton. In 2002 I wanted to drop weight and ordered a Caribow Tiaga (59#), and sold both of the other bows. The Howatt was a fine shooting bow and if I could do it all over again I would keep the Howatt and not get the Bighorn (which was a good bow, but the draw weight and physical weight in hindsight were poor choices). I envy you your new bow and trust you will enjoy it.
