Godwin A1? pump

I picked this up yesterday...



I believe it's an A1 model, but when searching the forum and google there a photo's with one or two receiver? chambers, so I'm not sure which model I have.

The lower part is non-ferrous (Brass?) which seems unusual, I was expecting cast iron with Brass plugs etc.

Any guesses to approximate build date(s)

Cheers.

1938 advert, may help or may just confuse the iss

Nice find! Been half looking for one of those for a while now. Yes some had one vessel some 2 not sure why.

Came in 3 different specs, A1, A1V and A1E. Basically the V was a Villiers powered set, the E and electric set and the A1 was a stand alone unit.

Interesting (or maybe not..) how the advert uses the Americanism 'Write us' rather than 'Write to us'.
