Default Mascon double action piston pump

Hello all
I was looking in the scrap yard out home the other day for some batteries and found a Mascon double action piston pump and, long story short, it came home with me.
when I got it home I could not believe there was no wear on the guide rods or piston rod, it wasn't seized and the pipes unscrewed. Even the greasers are there.
I took the valve caps off, tipped the flaky rust out and everything looks good. As per usual I didn't have time to have a look into the guts to see how the bore is but I reckon it'll be OK. Sadly it's been converted to a V belt (it was broken) so flat belt pullies are gone.
Now I'm back in Brisbane I've been trying to look into the Mascon pump history and found there isn't much information available out there. About all I could get was they were made and sold by McPhersons. Is this correct? I thought it is but better to ask then to assume wrong information. McPhersons also sold Ajax didn't they?
The pump I found under the heavy steel pile is a 2E which I assume is a 2 inch bore and I reckon it's about a 4 inch stroke. The outlet is about 1 1/2 if my memory serves me well. It was all a bit of a hurry. Finding it in the heavy steel pile was kinda appropriate. It weighs 96kgs.
Nearly all the Macson pumps I found on the net were huge. 5x5 and the like. By looking at the ad it seems that they made 5 sizes.
I did find a couple of ads and one ad was for 1936 and McPhersons did not advertise Ajax pumps but the ad had pumps which I've seen as Ajax pumps.
So did McPhersons make Macson pumps and later renamed them Ajax or what's the story?
Cheers and thanks
PS: didn't find any good batteries if your wondering.
