Peterson Hungarian/ Oom Paul shapes.
To explain the 'Oom Paul' label, it was a designation given to a 19th century South African politician named Paul Kruger, their first President. He smoked a pipe shaped similar to what's called the Oom Paul or Hungarian today. 'Oom' in Afrikaans, means uncle.
Many prefer the term Hungarian over Oom Paul, since the pipe's history is more appealing than the history of the man, with it's connotations of racism and association with apartheid.
The Oom Paul is a very distinctive pipe shape, with the chimney stack bowl on the true Hungarians, being almost parallel with the stem. It appears to be one of those shapes that has as many detractors as followers. Personally, I love them, being a sucker for any full bent shape(except the Cavalier).
A full-bent Oom Paul pipe.
Such pipes are usually described by the fraction of 90 degrees they depart from being a straight.
Very few pipes are/have true 90 degree bends, and are generally wrongly listed as Oom Pauls or Hungarians. Others are extremely deeply bent billiard-bowled pipes.Some Petes such as the XL23 shaped Le Strade, are often wrongly referred to as being Oom Pauls. Here are some examples of some of my true ones.
My favourite Oom Pauls,top gold Millennium (unsmoked),centre 1946 Pre republic,last Shamrock 1938.
As a clenchers pipe, they are terrific. Often criticised for not passing the pipe cleaner test,I have overcome any such problem by using fine Falcon pipe cleaners which pass without any problems.
They are amongst my favourite smoking pipes, great pipes for a long reading session with a favourite book.
