I’d imagine it looked less janky and more sturdy when it was new.

See the screws? That’s carbon-reinforced iron right there!

Its on wheels in part so the recoil rolls it backwards.

I’m not 100% sure but it also looks like a fairly modern canon, modernity being the period from 16th to early 20th C

That giant ass vertical screw in the back looks pretty solid. If there’s a similar one in the front I’d think this thing is good.
