I own an R Groves & Sons dovetail saw (10 inch, 16 tpi, nice open handle).
I bought it earlier this year from secondhandtools.co.uk (no affiliation) after being warned by my tutor about buying used saws and the inevitable kink/bend in them (I didn't listen, bought a couple off ebay that looked good from the pics but weren't as straight as I'd would have liked them). I was searching for a decent dovetail saw, couldn't afford the Adria or LN options and happened upon the Groves one. I did a little research and seem to recall one user in forum ?? (I've had another trawl of the web but couldn't locate the post, sorry not much help there) mentioned that these saws were the design basis for the Independence LN saws. Could be a load of cr*p but they certainly look very similar.
As for performance, it cuts very nicely indeed but erm... I haven't used it much recently, lack of workbench aside (it's in storage) I gave my tutor the saw so he could take it to his saw doctor before college ended (June), hopefully I'll be re-united with it in early October!
Cheers
