These appear to be Victorian era outdoor chairs !! Each piece is cast then attached with screws or bolts,,is that correct ?? If I were to guess,, it looks like original paint on this one or can you see any other color between the top coat and the bare metal ?? If you re-paint you lose 30 to 50% of any value !! I would leave them as is,, just clean them with any good spray cleaner then let dry, apply a light coat of oil, then wipe off excess well !! They are charming as-is !! Where did you find these chairs ?? Can you post a pic of the other one ?? Are those ball & claw feet ?? Look on the underside of the seat or on the cameo back for a foundry mark !!

Thank you “marthahill” for your reply.

I am currently in Bali and found those in a second hand shop.
The paint seems to be original and the feet are claw feet (see pics).
What’s the difference between the claw feet and ball feet ?
I couldn’t find any foundry marks but will take another look when they are delivered next week and let you know and I”ll also take your advice to keep it in its original condition.

As for the second chair, it looks like some modifications / re-welding was done and I might consider cleaning it up and repainting this one.

I also found this set of cast iron chairs and very tempted to negotiate a price for them with the same seller.
They are in good condition and are very heavy but they have been repainted sometime in the past.

What do you think ?
Is it worth looking into further ?
Thank you

Here are a couple more pictures

If you will notice the claw does not touch the ground,, it has the ball in its talons !! A claw foot would touch the ground without the ball !! The ball and claw foot has been used from late 1700`s to the 1940`s here in the U.S.,,It was almost a trademark for Duncan Phyfe !! But he didn`t make cast iron furniture !! I would not touch either chair !! Small repairs are to be expected in antique furniture and are part of its charm !! Collectors will buy a chair like this even with repairs as long as paint is original,!! And for a higher price !! But that said,, they are your chairs and the shabby chic look may not be your design taste !! So make yourself happy with them and repaint if that’s more to your liking !! Just as long as you know the pro`s and cons !!
