I just received an unused 1950 Primus 110. Here's the pic:

I think this is the type of stove that adi has that we were talking about in the spiritbrannare discussion a few weeks ago. It's really quite a pretty stove, nickel plated, collapsible and with the tank carrying handle. It's a big tank; I probably would not have bought one this size but for the unlit condition, the finish, and the lack of bidding, but I'm glad I did, it's a real beauty.
Now my question; I assume Peter and Ross will know. What was the niche of this particular model in the constellation of Primus products? It's just a bit "different" than other models.

Well, mine is a very dirty and incomplete 107. These stove had several advantages over the normal ones: you can change from roarer to silenat and back easily, it's adjustable (well, supposed to be) and it's self-pricking.

I think they would have been used just like any other medium sized stove. Camping, picnics, in the kitchen, wherever.

Hi Ed,
The 110 was a heater & stove combo. It was supplied with a bowl reflectors, guard & heat diffuser as standard as well as the three legs & pan ring. They are a really nice piece of kit. I have one here but I had to replace the burner with a conventional silent. I use it regularly every winter as a heater - lovely sound with an great glow from the reflector.
Stick Primus 110 in the site search & it will put up a few catalogue references for you. It uses the same burner as Adi's 107 & burns kero.

The catalogue says it's chromium plated; we discussed this point a few weeks ago. It does seem shinier than nickel.
Well, maybe heater attachments will show up sometime. But then I'd have to light it!

A good buy, indeed, Ed. I have a couple of Nos. 110 here (both chrome plated). The model remained in the catalogue for a quite a long time, and was useful both as a stove and as a heater. In some ways it was a dinosaur: the design with the cleaning needle in the burner stem was really superceded in almost every other model by the patented self-cleaning burner (commonest example being Primus No.4155). The No.110 is a 1920 design which outlived all its brethren (like the No. 107). But to find one of these in pristine, unused condition! That's almost miraculous.

This is part of the fun; now and then all of us get a particularly good one for a good price. While prices have been down, very generally speaking, the exception is for NIB stoves. This one didn't generate much interest, or passed under the radar as sometimes happens.
It's also enjoyable when you've collected awhile to get a new type, with some different burner features, etc.
As for being somewhat of a dinosaur, that's even better, because I'm more than somewhat of one myself!

I was really tempted to bid on the very same item!

Glad you won!

I was given a stove for repairs, it turned out to be the same stove as that 110. Not in as good as condition I might add. The top of the burner had came away from the lower part with the thread on. This section was steel and rusted all away. This is what I had to repair first. The silant burner had the inner ring only. Now I know the outer ring has 5 rows of holes not the normal 4 rows. This was a problem.
Thanks to Ross's site here I made contact with a (now good) friend who suplyed the right flame spreader and pricker.
A week after recieving this stove I picked up a 2 burner Primus 117 in the case with the same burners and the same 5 rows of holes in the outer spreader.
These are the first 5 row burner I have seen.
Has these stoves that you blokes are talking about got 5 rows of holes in the outer flame spreader as well? Albert

Just checked; yes, the dome on the 110 has five rows of holes, unlike the 4-hole standard on most silents. What's the significance of this?

On my Russian Primus (a phoebus clone) the bottom row of holes has half as many holes in it as the other ones, so ther's more space between them. When i tried it with a normal SVEA dome, it just burned yellow.

However, the dome on my Phoebus 625 has four rows, and all rows have the same number of holes. Its outer dome is apparently identical to the ones on Optimus 45 and Hipolito #1 (but I haven't tried switching domes). It burns just fine. The number of holes (and rows) must be somehow correlated with other stove characteristics like jet diameter and riser tube length. Anybody have expertise in this subject?

No mystery here: the bigger the burner, the more rows of holes. So, the old Primus burner:
No. 4138 had four rows
No. 4140 had five rows
No. 4142 (used on the biggest 7 pint model) had six.

Look at the Primus burner chart for more info.
It's all there on the chart!

i have litriture here on a Primus 110 It shows a 5 row burner, with part number 4209. I can't see a burner for the 110 with a spreader that has this part number. The only 5 row spreaders I can find is 4205 and 6, not 4209. Is there any differance

Burner 4209 is the correct burner for the 110 but unfortunately it predates the burner-chart on the site.
Maybe Ed can do some checking & see if any of the other caps fit.
It is quite common to find this burner without the caps. To get mine working I had to remove the cleaning needle which was damaged anyway & fit a conventional Hipolito silent burner. This makes the control cock redundant.

If Ed can't shed any light on the situation I will try a 5 row spreader I got from Sweden. There can't be much of a differance. I may have to drill the holes out larger. They fisicly fit.
