Hey Castor,

Here's a pic, you can place a 1.25" ep in the large end, the smaller end
might measure a lil small for you it's outer radius measure 15/16th or a
wisker under 24mm.

Although the pictures dont show it there is a hole for a set screw. From
memory it was lost after I tightened an ep in it and stripped the thread.

If it's any good to you, pm me where you want me to post it and I'll send
it off next time I'm in town, prolly Tuesday or Wednesday.

regards,CS
