Spear and Jackson Back Saw

For a long time I have wanted a nice back saw for detailed dovetail work and have over the past 12 months  picked up lots of them at garage sales, and rejected them all - too rusty, bent blade, missing teeth, broken handle etc. If I had found the right one I would have been prepared to pay well. But none turned up ---- until today at the market (and can you believe it ) hiding under a thick coating of grime on the 3 for $5 table, a beautiful tittle Spear and Jackson back saw.  Yooohooo!!!!
