I did think about it a bit, and since the company is long gone, having been eaten up by BAE, and the copyright on the Vickers Machine Gun is well expired too, I thought it'd be safe to do so. Even then, there is the addition of the apostrophe to the name of this submission. The original founder of the company was named "Edward Vickers", with the 's' at the end being part of the name, rather than an addition to turn it into a possessive noun.
The selection of the name was deliberate. Yes, the name is a tribute to the Vickers Machine Gun, and yes, it is not original naming. I still chose to go with this, as In-Character, the Ottyo are deliberately mimicking the British Empire for their own reasons. OOC, I'm having it as part of the narrative that I've thought up for them.
If it's still too close for comfort, say so and I'll figure something out.
