Hello TH44, this is an old post so don't know if you are still active on the the forum.

I enjoyed the post on the Lee particularly in that I have the brother to your rifle (cost me more than ten pounds though) mine is marked Westley Richards and has the Ser No 38060.

It appears to be pretty much a twin of your rifle.

I bought it in Canada otherwise don't know much about it.

If you have any information I would be interested.

NB
