OK I found some specs about the aquarious:
Produced by "Royal";
WS 67"
Length: 50"
5-6 channels
.60 engine
weight: 6-7 LBS
Design: Late 60's? (it's a vintage pattern plane - and looks so)
The matching equipment that I have for it is OS SF 61 Pump and air retracts.

Opinions/reviews/recommendations from (old) pattern fliers will be appreciated.
