Two Roman saws from London; Thames and the Bank of England

Testing two reconstructed Roman one piece saws from London made by Daegrad Tools, one from the Thames foreshore now in the Museum of London (afraid there is no further information) and a curved push pull saw from the bank of England; SAW20 (BoE199), see Humfreys ; London's Roman tools (excellent read BTW), both saws available from the various Daegrad Tools sites.
