A pipe smoker since 14 y.o., Karl Erik moved to Kenia in 1962 during the war in that country and for the next 3 years among other deprivations he was unable to procure pipes. Under such unfavourable conditions he had a time to convert his small hobby into a professional pipe carving experience and since 1965-66 Karl Erik started selling pipes to Copenhagen pipe stores.
That's interesting that Karl Erik's old lathe was obtained by Tom Eltang, who had an idea to equip a small workshop and make a series of good and interesting pipes for a reasonable price. This series was named "Sara Eltang".
The pipe bears the old stamping with the grade 3 thus it was made the most probably before 1990.
The pipe markings are "Karl Erik \ HANDMADE IN DENMARK \ 3". The length is 13.2 cm (5.2"), bowl's height is 5.1 cm (2"). External diameter of the bowl is 4.4 cm (1.73"), internal diameter is 2.2 cm (0.87"). The depth is 4.5 cm (1.77") and this pipe weights 52 gr. Briar, vulcanite stem, 9 mm filter. The bowl had a few small chips carefully and reliably patched during the restoration.
