Here you are : Optimus No 4
Hi Ian, I like your Op.4. Lovely stove. I take it thay you are running with a "Con" silent burner cap.
Check your fuel filler cap with the one shown in this post:
It should help in dating your stove.
I note that the riser tube of your stove has a solder repair. This joint appears to have been the point of weakness on these No.4 stoves as I have seen several with solder repairs in this location.
Thanks for sharing images of your "new" stove.
The burner cap is from a Primus 4, and the Primus stove is dated U13, which is in absolute brilliant nick.
I am waiting on getting three silent burner caps, from Base Camp, 2 of which I understand are marked Primus, and 1 unmarked, which will go on the Optimus 4.
The burner head which was with Op 4, is from a Primus dated AD1, so I have transferred that to the Primus 4, which seems the appropriate thing to do.
The filler cap was from a Primus on the Op 4, so I had a spare Optimus filler cap, so I put that on. but its not the filler cap as in the pictures on your stove.
The solder repairs I can clean up no problem, although its is slightly more difficult than on a 2 pint stove.
Normally I would soften the solder up with a blowtorch, and then drag it off with a soft wire brush, but with the Op 4, I'll have to use small files.
Perhaps 800 wet and dry with paraffin as a lubricant, as I find water badly stains, then use 1200 grade to finish off.
Then I polish up with Brasso.
