I have been looking for these models for a while. Especially the 886UH. I was lucky enough to find both brand new in the box just recently. Together they make a beautiful set.
I found an 886UH with out the box many years ago.
It took years to find that set in the boxes.
They were made by Camillus, using Schrade's old tang stamp... Ken
This is from an old post, here on Blade Forums.
"Here is the response from Schrade on the 886UH I have just acquired.
The model 886UH was not a regular product in the Uncle Henry line, but it was a specially ordered Uncle Henry item that was manufactured exclusively in the very early 1980's (probably around 1982) for a hardware distribution chain across the U.S. that are now out of business (I believe it might have been Belknap). It was not considered to be a high quality product, as this chain was looking for a "low-end", "low-cost" item, and so it was specially made for them. There was a total of about 30,000 of these items shipped during that time, so they can be considered to be fairly collectible. I guess it could be considered to be a limited edition knife, even though it was not manufactured as such. The retail at that time was only about $18.00. There was no Loss Warranty included with these knives, but if someone did claim a loss, we still honored it.
I hope this is helpful, and if we can be of any further assistance, please let us know.
Best Regards,
IMPERIAL SCHRADE CORP."
