Welcome to the Forum,
That was Bob's own retail outlet when they were made on a larger scale in Eugene. I'd frame that Invoice. Thanks for sharing.
The Warranty card I would say was filled out by the owner. First, the Invoice is marked "picked up". The card is marked that local codes were not checked. Bob would know them or mark them checked. I'm sure he would have signed the card, and taken it with him. Why leave it with the customer to mail to your company when you would take the card back with you? Plus by then Bob had many employees and was busy with UL Listing his stoves. Goldilocks had just been invented and certified for mobile home use, and corporately he would be busy running quite a large company by then. I would think his own installation days were over in 74 or 75.
The Bear Legs were an optional accessory to be installed in place of the bolt on "Straight" leg. The other optional leg was the "Furniture" style shown in this 1980 brochure.
I watch eBay very closely for them and if they came from there, I believe these pictures are others from the auction where you found them, I can tell you the story on them;
I can tell you these were sold from CA and first listed as only 2 "bead blasted and painted with Rutland paint from CO" for $200. The auction was only listed for a short time and I messaged the seller telling him they were only a half set. He thought they were only for the front since they face forward and back when installed, unlike the feet that can all face forward as if on the animal. He thought they possibly made a rear set facing forward, but I assured him that was not the case. The new auction listed was for 4 and he mentioned in the auction he was corrected that they were not only for the front, and added "but what do I know". When put back up again the words "bead blasted and painted with Rutland paint" was removed. I bought what was left over from production from the Woodland Park CO. fabricator years ago. There were a few sets of the Bear Legs, doors and bent tops quite rusty that I turned down. They would need blasting and I was afraid it would take away from the detail. For $10 each plus shipping to PA they were not worth it at the time. Nice sets were selling for 60 to 100 at the time. I never dreamed they would someday sell for $100 each........... The sets I cleaned up to sell went for $100 a set back then. The person who eventually ended up with what I didn't buy is in CA.
