A new one for me

Is the fill plug angled out the side of the boiler to prevent over-filling?
Also looks like the firebox venting was made by drilling two holes near each other and no filing away the extra afterward.

Very neat find!
A newie to me as well Jan, a worthy addition to your collection.
An interesting find Jan , looking forward to the video 😊
Very nice Jan ... looks to be fairly low mileage for age. The cylinder assembly looks a bit like ones seen on ADE engines, so I wonder about any relationship possibilities there. Also, Id say that drilling two holes overlapping is a bit of a PITA and quite time consuming, so I wonder if those firebox holes might not be stamped out/knocks out like in an electrical box.
I must add that the burner looks just like the tins that fillet of anchovies comes in here!
Another manufacturer (or: retailer) added to the list...
Thanks for sharing this!
Very interesting Jan.
Another Maer with which I was not familiar.
Have you steamed it yet?
