You still need a snaplock adaptor - you are best to stay away from lock in taps - more chioce for pushin.
By the looks of it - your font is non flooded.
If it helps - i sell SS Snaplock adaptors 35.00 ea or 3 for 100.00 and they screw in.
S/H Flortye taps are 65.00 ea or brand new are 95.00.
But this price does not include handles.
This will give you a guide at least when bidding on eBay etc.
Do you have a reg yet - Harris Dual gauge are 82.50ea.
