I am no expert, so please accept my ignorance on this question. I have gotten a T-34 bug and have gotten a couple kits. I started working on the 1/35 Maquette T-34/85 with Mine Roller recently. I did not like all the flash so I looked online for a turned metal barrel. Found one from a company I personally was not familiar with, Como.
Anyhow, I then was able to get a DML kit of the same tank (wo the roller).
In looking at the barrel parts (it has both the slide mold and turned metal ones), they are very different from the Como one (which in Google searches, I found another turned metal that looks similar).
Please look at my picture and let me know if any/none, whatever is right.

Thanks.
John
