Hi, This is a Shinabro 340, one-pint capacity, paraffin fuelled, cased stove, which I have been working on recently. The Shinabro 340 is an Optimus No.00 clone, but there is one very significant and crucial difference, the burner-to-upstand joint on the Shinabro has a left-hand thread! How many Shinabro burners have been destroyed by users who never knew of this design quirk? The joint between the upstand and tank has the more conventional right-hand thread. I believe that this stove dates from the 1960s/70s and they were popular in the UK with youth organisations. This particular stove had a very rusted case, with a Leeds City Scout troop identity painted on it. I re-painted the case, replaced the stove washers and seals and generally tidied up the outfit. Here are some photos: This is a well-made stove, with a nice sturdy case. Best Regards, Kerophile.
