Hi Everyone,
I found this Bladon B61 Petrol Blowtorch in November 2012 at an antiques fair. Before I saw it I had thought that all blowtorches ran on paraffin. In searching for information on these I came across the BLADON B59 by brian1967 in this site.
Then I fired mine up - didn't do any maintenance, but checked it for leaks as it pressured up. It works well as you can see from the photos.
Mine does not appear to have a date on it. Brian, if you read this, can you tell me please, where on your B59 the date is shown.
