Uh, you know it doesn't say. There is every implication that it is infact the Mk 105s you have here.
The A. D. Baker drawing shows it to be a twin (I have the drawing infront of me). I think that in the resize of the source several close lines greyed out and make it hard to visualize.

That said, I think they 40mm Bofors does match up well:

Looks good thus far, Thiel, keep up the good work!

Almost there. The SPS-10 is a bit of a guess but it matches the drawing fairly well.

Source Materiel is always welcome.

Per St. Norman, "Deliveries began in October 1953, and it was considered so effective in ASW operations that SPS-10 was to equip 25 per cent of all ASW vessels by the end of 1956."

She commissioned before SPS-10 was available, and certainly would have been very low-priority for the upgrade. Given that she went out of commission in 1969 (and spent 1960-1965 in reserve), I would be somewhat surprised if she ever received SPS-10. Much more likely to me would be SG-6, SPS-4 or SPS-5.

This time with boats.

The rockects atop the drawing are bit pretentious and not fitting to the purpose. Otherwise great drawing

I think five is maybe a bit much, but I'd keep one of them IMHO.
