Hi, Mark,

When you said Webley Eagle did you mean Falcon, made from '62 to '71? Have both myself, reckon the Webley is better made. Think the Meteor was cheaper, hence them selling in millions. Haven't seen a Falcon in .177. The Thrale book says they are scarce compared to the .22.
Regarding the opens on the Meteor, I've got a (stalled) resto on one of a similar age ('69-73, if the SN is TE), but the sights are fine. I'll be keeping the opens when I get round to the rebuild, but sure I've seen them advertised, or ones that'll fit.
