I recently had a chance to discuss and get pictures of a really nice old Hill... real old. It's owner is Ken Elshof. This is a circa 1939 Hill. Here is what Ken has to say about it:

Richard,

Sorry I didn't get these to you earlier.. Grand kids kidnapped me this morning and made me take them fishing.
Great day and even better that I don't have to clean fish.
I bought the bow off eBay, from a dealer in the Seattle area. He advertised it as "Fresh from the Great Collectors Estate in Hollywood"
He could not or would not elaborate any more as to whom that was??
It is laminated Bamboo with the nodes clearly visible.. Backing is a brown fibrous material with what looks like a layer of some black plastic or bituminous substance under it. The backing is worn thru in the nocks and you can see a crack in it about 3-4" below the upper nock.
The picture in Craig's book definitely dates it to the late 30's era with the silk binding.
Documentation on the heads is weak, but they look very similar to the Broadhead arrow sold in 1942 in Ben Pearson's catalogue. Trouble is there is no documentation the heads were sold separately and the arrows are definitely not the Howard Hill/ Ben Pearson arrow. Wade has one of those but the head is broken off.
We did find that in 1939 Viking Archery in San Francisco advertised as being the sole distributor of Howard Hill archery equipment.
Viking was owned and operated by Bill Wright who accompanied Fred and Glen on the little Delta hunt in 1959.. He shot a huge moose, but little else is know of him. Glen went to see Bill shortly before he passed  and Bill donated most to all of his remaining archery equipment to Glen's museum which is now the Pope and Young museum in Chatfield, MN.

This and next picture are pages from Craig Ekins book "Howard Hill - the Man and the Legend" "Bamboo bow built around 1939 for Frank Garske. The wrapping were for added support of the facing and backing."
Here is the arrow head Ken discusses...
