Weld bead on bore evacuator on T-55’s.
Some have it, some don’t.
Maybe a manufacturing issue, which factory made it?
Opened for maintenance/modification and then welded shut again?
Hard to find photos of the same tank from two sides, in case the weld bead
was randomly placed left or right.
Edit: Fixed some typos, I was in a hurry when I created this post, DANG …
I think so. I was looking at photos and noticed it as well.
Finally found one in a museum with photos shoing both sides of the barrel of the same tank.
There is one here:
sporting what seams to be a weld bead around the 7 -7:15 position (seen from the front)
Just got back home from Prague! 3D prints from last week:
Some clear prints in 1/35
AMX light indicator parts:
Welcome home James! Hope all is well in Prague?
Welcome back James, hope the trip went well.
The clear parts look great. 
I was not going to CAD stuff for WWII Axis vehicles in 1/35 but with the generosity of @ MacFheargais’s STL files to improve Italeri’s Semovente M40 kit, I recently obtained the kit and planned to upgrade the parts with Grandd’s designs.
One main part not available for 3D printing was the main 75mm gun so I decided to CAD and 3D print it. The kit part is not great. Some CAD screenshots:

M48 and M60 MBT steel wheel mask for 1/35 kits - measurements based on Dragon and Tamiya kits.
Looks good.
Great idea-I would think anything German would be popular.
Noooo WW2 German, Dan!! That’s an insult to my generosity with time for this “modern” armor accessory! 
Gotcha!
M1A2 Abrams SEP V2 or V3 CITV wiring conduit for Rye Field Kits in 1/35 scale.
Not a fancy design but for those who care - RFM kits are completely missing this part when Academy, Meng, and VOIIO kits have it. The dimensions are based on S20 of Meng Abrams kit:
STL will be available on my cults3D page.

HA!
Great stuff, as always. The physical mask is very interesting. Looks like it works great.
How was measuring vs. printing? As in, tolerance/shrinkage? I’ve never had to print “fit” things before. I did a little testing, but I don’t have a formula (as in, 2mm hole prints 1.95, etc.).
Hi Wink,
I feel like FDM prints are less prone to shrinkage than resin prints and using more flexible plastic provides a bit more room to fit things. It’s all trial and error for me. Thanks for your kind words.
The classic.
