Does anyone recognise/know the maker of these torches?

[Jeff]

Hi all!
I recently bought a couple of gas torches for a really cheap price, as the seller did not know what make they are. Does anyone here recognise either of the torches? (or know if they're any good). If it helps at all they came from a school technology department, and no maker's marks are visible.
Thanks! :)

Top looks like a Town Gas or natural gas/air torch, the bottom one is a oxy/acetylene lamp workers torch, the only thing that would render them unusable would be if the seats in the valves are worn and not sealing, you maybe able find spare parts

I'd go back to the school and ask them what they ran them on if at all possible.
My Flamefast was originally jetted for NG; I had it redone for propane - but there was no visible indication as to which it ran on.
