Hi Dick,
I thought some shots of my older Hill bows might be of interest to the members..
The 5 Hill bows pictures represent Hill bows that date  from the 50's thru the 80's.  
From the left, the first bow is the Green Dragon that has been referenced in another section.  It is made by Howard Hill in around the mid 1950's.  The next bow could be a twin of the Green Dragon in that the design is very similar.   I'm not sure of the maker, possibly a Shultz bow, but it appears to have Howard Hill's signature on the limb.   Even though Howard Hill didn't make all the bows when he started his business,  it was a common practice for him to sign the bows back in the early years.  The next bow is from the 1960's when Howard Hill productions were located in Sunland, Ca.  I believe this is a Shultz bow.   It  has the recurve decal on the limb, no writing.  I also have another bow identical to this one  except for a lighter, 55# draw weight.   The fourth bow is an early Tembo from the late sixties or early seventies.  It is made by John Shultz.   Definitely one of my best shooters.   The last bow is a Big 5  I had made by Craig back in the mid eighties.  
I have also included a separate picture of the Green Dragon  along with an early Hill broadhead.
