I have a 6v ingition amplifier on the Morris. It uses the original points but no condenser . The Morris runs so much better with it. I will PM you with my number. _________________ 1936 Morris 8 Series 1

Electronic ignition units are available and should fit, might help?

Are they available for 6v?

Hi Rick
Regarding these add on units I agree with Nick, they do make a difference. The way they work is quite simple; on a conventional ignition when the points open the, the field in the coil collapses and the energy released to fire the plug, the "punch" is dependent on 2 factors, firstly how much energy you got in the coil when the points were closed and secondly how quickly the field in the coil collapses.
This type of unit uses a transistor to switch the current on and off to the coil (traditionally what the points do) the points now just switch the transistor.
The benefit of transistor switching is 2 fold; firstly the transistor has less resistance than points, so you will get more energy in to the coil, secondly when the points open the transistor switches off instantly (traditional points don't) promoting a faster field collapse in the coil.
An analogy would be blowing up a balloon and then popping it, the more air you get in and the more instant the deflation; the louder the bang!
A couple of misconnections about electronic ignition, firstly you are not increasing the coil secondary voltage, when the coil field collapses the voltages rises across the spark plug until it is large enough to fire it; this is governed by the gap, the compression, the air fuel mix , and the state of the plug. Secondly the only ignition problem this sort of electronic ignition unit will fix, is a doggy condenser or perhaps doggy points, you do need to get to the root of the problem first.
If you want to stick the jolly green giant on an engine scope, let me know, it takes a lot of the guess work out with this sort of problem.

If you are having trouble with the engine at higher revs then suspect the condenser, even new ones can be s**t. _________________ 1936 Morris 8 Series 1

Gordon,
As I recall, you were looking for some wheels for the car carrier bus? It may be worth a trip to the breakers to look at wheels from a late 60's early 70's Volvo F86. These use a 20" 10 stud wheel on a 285mm PCD which is the USA standard pattern. Translates to 11.25" PCD. I'm not sure on the Dodge PCD, but Volvo used this standard when trying to break into the USA market, so it might be a lead to follow up on. If they fit, they should also fit the larger trucks and possibly the Burma Dodge.

Thanks for the info Gordon, will pop that on file.
Michael Ware (journalist/author/former Beaulieu curator) came by today to get some info for a write-up he's hoping to do on the old girl. Nice to have a chat with him, he met Poore a few times many years ago when Beaulieu were restoring the Poore family's vintage Argyll car.

although there are tow hooks, the front metal is 1941-47, and there have been `DODGE signs on the sides of the hood which shows the hood matches the front metal. Different front wheel too?
I'd guess a 1941-47 WK heavy duty 3 ton, possibly ex-military, given the tow hooks.

If it's Canadian and 3-ton wouldn't it be a D60L? If it's American I'd have guessed at a 2-ton truck looking at it, is the front axle wide enough for a 3t US truck?

Absolutely NOT A D60 is the light duty 3 ton T110L, either long or short wheelbase, with the 236 cu in engine.
That's a full sized heavy duty 3 ton like Bess, I assume with the 331, although it does look to have been supplied to / via Canada and have Canadian / British / Commonwealth pattern wheels on the front. A further post suggests 1944 date and Canadian Army use.
Note in particular that is does seem to have a windscreen cowl on it, like Bess, and not a cut-down or cobbled up cab.

Interesting stuff. I didn't realise that the Canadian 3t trucks had the 331 but I've not researched them in great depth
"Uncle Alec" tipped me off that the old girl gets a mention in this month's Classic Motor Monthly paper. As a result of the article two people have been in touch, one contacted me via HMG paints and remembers visiting Poore's pad in London (he used to fix their electric garage door!), while another got in touch whose father used to run this model of Dodge (flatbed versions) in the 50s, and has a cylinder head in his shed going spare.

I remember the head on Bess had a repair on it anyway, so a spare would be useful - no like there would be a big market for a spare head, even worldwide.

. The Morris runs so much better with it. I will PM you with my number.
