Default Telephone Relays

I have a few rather nice relays , possibly from an exchange, no photo at present. Dated 1961.

I wonder as to the value of these?

You could have a look at completed listings on eBay and the like to see whether similar ones have sold and for what price. A lot will depend on whether someone is looking for what you have - or can use them to make up something.

If the tip of each blade leaf has a small V notch, most likely platinum contact points. Note, not all leafs had them, even if just one pair does.
Just adds to their value. Not likely to make a difference to actually being used by enthusiasts.

I have several NOS boxed PO3000 relays as well as a few used ones in working condition: slugged toe; slugged heel; high resistance; low resistance...

They were spares for the Marconi 250kW BD272 / 6122 HF transmitters which used lots of PO3000 relays stacked in vertical banks in grey steel boxes for their control systems, almost the same configuration as in a UAX13 telephone exchange.

If yours are similar, you might find interest as to what they're worth at telecomms swap-meets as they're still sought after for projects. Or could see what the 'sold' price is typically on Ebay, when they come up?

Thank you Russell, I think mine are other than PO 3000 and yes, I must get pictures of same. They are nothing like what I have seen elsewhere, which seem to start from £5.99.
