So I'm preparing to build as accurate a backpack as possible to replace my old SWAT approved one which is somewhat dated now.
Using the references, I think I have scaled most sizes within a certain tolerance. I used the known sizes of the radio and the syphon as comparisons.
If anyone sees any major discrepancies from what I think, please let me know your views.
FRAME:
Top to bend: 260mm
Bottom to bend: 220mm
BREXTON BOX:
Height: 240mm
TOP BOTTLE:
126mm showing below mushroom cap
MORTAR TUBE:
687mm Long with hole 45mm below top
EXHAUST PORT (main body):
120mm at longest point, slopes to 111mm
60mm wide
I think the rest is fairly self explanatory but if anyone wants to chip in with other dimensions, feel free
