Hi Guy,
It seems Webley air pistol prices are still quite buoyant, but I still can't help feeling the world has gone a bit mad.
I originally estimated the cased, post-war Senior at £600 hammer so around £1000 with costs which put me in my place. I felt better when the pre-war cased Senior with incorrect oil can sold for £1,500 as I have a similar pistol with original accessories which cost me a good deal less than that when I bought it.
Regards
Brian
