White M3A1 AOP Windshield and Door armour

[Big D]

Hi Andrew

I am pretty sure much of the armour on the M2A1 halftrack is the same as that on the M3A1 scout car. Maybe someone else can confirm?

Otherwise, could I send you the outer dimensions of the door and windshield and see if they are the same as yours?

Thanks.

Hi Darryl, I have a windshield armour plate that l hope is not too inaccessible, it's in amongst a pile of stuff. I'll see if I can hook it out and get the measurements for you.

From what I know of half tracks I believe there is very little that will fit the scout car although it looks the same.

Hey Andrew

I've confirmed what David has said in that the halftrack armour is different to the scout car.

Sorry to waste your time.

Thanks.

I find that hard to believe, seeing the design and production of both the Scout Car and Half Track was done by White?!?

Whatever, ignore my remark as I am no specialist on this subject and cannot contribute with measurements etc.

Hanno maybe the design was "improved" as there were a few years between the first production of each. Correct?

Ok Darryl, I've got the windshield armour out and still have all my fingers and toes so here are some measurements. More to follow as I work out exactly what you want.
All references are assuming the armour is standing upright on its lower edge.
This piece of armour is thicker than that used on most of the hull being 1/2 " thick or possibly a few thousandths of an inch less.
Basic dimensions are 13-1/4 " top to bottom.
62-7/8 " across the top.
60 " across lower edge.
Top edge is square. Lower edge is beveled at an angle of 55 degrees inclusive. i.e. 35 degrees from square with the 'chisel' edge on the front face.
Distance between view ports, from the nearest edge of one to the nearest edge of the other 32". View ports as stated are 8" X 3-1/2".
Wiper slots are 1/2" wide X 1" top to bottom. This puts the centre of the radius at 3/4" up from the lower edge of the visor as the top of the slot is radiused. (1/4" radii).
The wiper slot is also counter bored on the rear face with a square ended tool 7/8" diameter to a depth of .230". This is a circular counter bore only and uses the same centre point as the upper radius, the step is not milled down to the end of the slot.
Distance of wiper slots centre to centre is 34-1/2". They are NOT centred below the view ports.
More to come

Hi David

Wow! Thanks for that. That is great. I'll start putting a sketch together.

I managed to lay my hands on some plans for the windshield and door armour for the half track. Like you say they are different. The measurements you've given me for the windshield are close to the halftrack windshield. The halftrack windshield armour is a little wider at 63 29/32". The shape of the folding door armour is quite different though and is flat along the top whereas the scout car is sloping. From what I can see though the viewing ports look to be the same.

By the way - how heavy was that windshield armour? Would it be a one person job to fit or does it need two?

Thanks again.

Cheers.
