More Chieftain's Hatchiness


Recommended Posts

 

Where did that drawing come from? I've never seen any actual plans of the proposed AC4 before.

 

 

National Australian Archives. Not the original drawings as far as I know, although they might have them too. It's a little sort of A5 sized booklet mostly AC3 some AC1 and that weird looking hull until you notice the Tank AC Mark IV in the corner, then it makes sense.

 

I'll have to figure out how to get a copy. I've been rather fascinated by the Sentinel ever since I saw the one at Bovington. I keep hoping someone is out there researching a book; we got one on the Ram (another one of my weird interests) after all!

I was in contact for a while with a bloke who wrote a book on the Australian Cruisers, I wanted to pick his brain over some of the details because what was publicly available at the time didn't make a whole lot of sense, but the publisher never did anything with it, I'm not sure what happened. The former, the resolution is a little low, 'cos there is more detail on the original but is free, so can't complain.

Oh dear, really Lindy? "It is clearly wider than the actual thing so they were lying"?

 

Admittedly, it's only the earlier 64" turret ring version, but it is an AC4 hull and the turret ring does extend over the sides of the hull by means of the air louvres.

Plans, armoured fighting vehicles at a guess.

Page 36 shows spaces on each side of the turret armour, possible more on page 86. That mystery slot in the turret armour might have something to do with the Water cooled MG's?

... might have something to do with the Water cooled MG's?

 

Only in the sense that it provides ventilation next to the coax and the loader. Keep in mind that that is a Mark 3 and the Mark 1 is different, the Mark 3 also uses that air vent as a means to dump steam from the coax cooling system. On the Mark 1 the cooling water tank is located further to the rear and I believe the steam vent is out the right rear corner air vent, which might have resulted in steam getting drawn back into the turret and could be the reason it was subsequently changed to something that actually resembles the setup in the Matilda.

It's good isn't it? :wub:

 

The NAA is slowly digitising their files, well it looks like most of the printed material they have at least. It's a bit hit and miss as to what they have but the ones with drawings are my favourite kind. Like AE1 and 2 general arrangement, an excessively precise 4.724 inch gun, an identification list for a 3.7 inch mounting, some aircraft engines Opel and a couple of Fiats 220hp and 650hp, and an apparently mad project for a Centurion with a sawn off 105mm for jungle use :blink: I suppose it would be alright for use with canister? A rifle mortar? That one looks like it would hurt. The Jefferies robot tank, an Aussie Goliath! And repeated suggestions to bomb the volcano at Rabaul with soap to cause an eruption :huh: was Wile E. Coyote around in the '40s? I know I can just google that, but I fear the answer might be no.

The 105 mm cneturion: short barrel makes a lot of sense. Did they plan to use just the original gun with shortened barrel or a specially designed one ? I do not see an advantage over using the 165 mm gun from the AVRE..

Just a regular 105mm L7 tank gun, or 20pdr, with the end of the barrel hacked off and a counter weight to keep it all balanced.

Fast and Furry-ous has been released in late '49, so barely in the forties.

I guess they were thinking with the short barreled Caenturion to use it a s a howitzer. An armoured assault gun in purpose.

I was at APG twice and will forever regret not realizing that the Elefant was sitting nearby on a train car. :( The fact that a picture I took of an M60A3's gunner's sight housing was used as an illustration in part 2 makes up for it a bit though. ;)

I'm guessing that the Chieftain's comments about the Covenanter are in response to the books put out by P M Knight.

Seeing the old M60 at a museum reminds me of my favorite museum story...

 

I remember being in OSUT for armor (M60A3!) at Ft. Knox in 1982. Being lucky, I volunteered (!) and was sent to the Armor Museum (the ones who didn't volunteer picked up litter all day :) where I spent the day dusting the exhibits. Being allowed to climb on the King Tiger, the Stug, and others was a delight. It was also where I decided I really liked the M8 Greyhound armored car. Not very practical, I admit, but I found it really cool and I've always had a softspot for the 37mm pop gun.

 

Someday I'll get to Bovington.

That could come in handy if your tank has a sudden case of 88, 76.2, 75. :)

 

 

More like 85, 100, or 115mm, given that the M43 was produced in the 1950's and 1960's. :D It's M37 parent vehicle (upgraded as the M37B1) saw use in the Vietnam War as a convoy section commanders vehicle, basically a small gun truck with 2-3 M60 GPMGs.

If you want time in Vandal or in a friend's cherry restored Daimler Dingo, let me know. We can make that happen in ways that will include road time. I suspect the Dingo drive would be in and around the DC environs.

"Door glass regulator handle." Reminds of what the Navy called an umbrella, "an anti-moisture personal protection device."

My favourite is "area denial submunition".
