This 92 year-old No.53 has a nickel plated steel tank that required some attention inside and out when I acquired it some years ago, due to corrosion. Fortunately, no perforation had occurred (unlike my No.50). Having dealt with the inner tank corrosion, it was then a question of how to go about dealing with the corrosion on the tank’s surface. Yes, I could chemically treat the iron oxide to make it inert, but my preference was to remove it completely - bearing in mind my intention was to retain the original nickel plating rather than re-plate. So into my electrolysis bath went the (sealed) tank which removed all the corrosion without adversely affecting any part of the nickel plating. The tank was then sealed with three clear lacquer coats to protect it. The ‘PRIMUS-SWEDEN-PRIMUS’ trivet. Overhead of that ‘unassuming’ tank stamping The No.4138 burner…with a No.4273 igniter ‘hanging on for dear life’. Primus Metal No.4205 outer cap and No.4676 inner. The removable stamped collar. Hidden under the collar is the date stamp: Y = 1934 A Primus 210 reserve cap was added by me, which in brass I believe goes reasonably well with the collar. Knurling patterns of the No.53… …and the brass pump rod (which on later models, a steel version was fitted). Instructions. Reverse side… No.4605 fuel jet prickers. Pharael.
