Armrests
It doesn't have Gunlocke's blocky armrests, which would lead me not to focus exclusively on Gunlocke. To be clear I don't think it rules out Gunlocke, but makes the likelihood of a positive Gunlocke identification low.
The grain on the armrest is unusual. It looks like a species I know it is not. Close-up shots of the wood might help determine what it is, which might help id the chair.
And where are you? (I assume the US, since it looks like an American chair, but if you aren't in the US, that would be interesting).
