Seeking dimensions for the Bazooka rocket
 
Working on the new edition of "Rockets of the World," I'm hoping to do a drawing of the famous WW II Bazooka rocket projectile. This would either be the M6A1 (live) or M7A1 (non-explosive training) version, which had identical external dimensions. I've seen the training version for sale on Ebay on several occasions, so I wonder if anyone here might have one, or know a collector or museum that might have on that they could measure. This is the rocket in question:



Here are the dimensions that I'm seeking:



The full resolution version is here: Bazooka Dimensions Needed

Thanks for any help anyone can come up with. (I already have the manual the drawing was taken from--there are some dimensions, but on close inspection, most aren't usable exterior dimensions)

Can't really help
 
But I admire you for going after the "tough" ones....

Good luck!

That last one should be it.

Lots of close up pics, lots of sub assemblies all with a ruler in most.

Actually, I don't think so . . .

From that drawing that Peter uploaded, I think he is looking to put calipers to an example in his possession, rather than just scaling photographs.

I have a casting of a bazooka warhead that I made from a mold of a bazooka warhead that I took from a real bazooka warhead. I took a mold of the fins also, but that didn't work well, so I don't have a casting of the fins.

Here are the measurements of the warhead that I just took from my casting. The big measurements may be +- 1 mm due to the mechanics of taking measurements from cones and cylinders.

P 9.1mm (.36") (to where sphere is tangent to cone, not the diameter of the sphere)
Q 16.1mm (.63")
T 58.4mm (2.3")

A 80mm (3.1")
B 102mm (4")
C 105mm (4.1")
D 116mm (4.5")
D + gap 120mm (4mm gap) (4.7")
D + distance to transition to conical section 36 + 4 + 116 = 156mm (6.1")
E 206mm

Diameter in gap 56mm (2.2")
Diameter at transition to conical section 57mm (2.2")
Diameter at base of warhead just above E 41mm (1.6")
(base of warhead, in region that ends at E, is just like a toroid)

My guess is that the measurements might have been specified in inches, so the 2.2" might really be 2.25", etc.

Crazy idea---
 
You could contact an owner and ask if you could borrow the rocket.

Yeah, crazy idea, but it might work. Never know unless you ask. You have certainly built up enough credentials as a rocket/missile historian and author to be worthy of trust.

Next crazy plan: group-sourcing the funds to buy one of these. Put me down for $50.

Thank you! I seem to have found someone who can take measurements of the whole rocket over on The Rocketry Forum, but his has a dented nose tip. Assuming yours has an intact hemispherical tip, this will provide the correction I need.

Thanks!

Alas, pictures with rulers in them aren't the same as actual measurements, unless the ruler is actually touching the object and running the length of the measurement.
