Best I can do, is guess. A V-105 pump would be round, so, I know that can't be it. The only thing I can find that might be close would be V210-5-1C-12-S214. That would be a vane pump. Rated @ 5.4gpm @ 100psi & 1200rpm, and 4.3gpm @ 2000psi & 1200rpm. And a max rpm of 1800. I'm not sure where the model number would be stamped.
