Patt: 18 scopes...Auzzie

This probably should be in the WTS section and if stepping on toes, please remove or delete this post. Does anyone have a buggered or parts for a Pattern 18 Auzzie scope? I have one in rebuild right now and am looking for a beater for parts that I can use for duplication and or use. I don't need any lenses, other than a decent diaphragm with cross hair and post, as I really don't want to cut out the lens and replace it with the wire and post. Done it but preferr correct diaphragm. Anyone put me onto a source or ?? Open to trade or outright purchase...
Thanks guys....
