Look in pretty good shape to have been buried !! Unless you mean buried under stuff !! They are pretty typical Victorian style lamps from mid 20`s or 30`s !! I have a similar pair in my garage !! Looks like may have been rewired,, do they have double strand wire ?? You can buy lamp kits to rewire them if needed and it will have the harp to hold the shade,, Or you can take a harp of same size from an old busted lamp !! Rewiring is quite simple to do !! They are a pretty common type and could have been made anywhere but they do not look Czech !! Almost all homes would have had similar lamps back then !! As to value,, $20. each,, $25. on a good day,, if you are lucky !! Would need to be rewired, have all parts to get that much !!
