Having a sort out at the back of my garage I came across two of my old blowlamps a Max Sievert and a Monitor, stripped them down and gave them a clean up, filled them with petrol and lo and behold both in perfect working condition. I bought the Max Sievert when I was 19 so that makes it 51 years old, the Monitor I would reckon to be about 60 or more years old, what do you think I should do with them? sell them on as collectors items or what?
