Tinker,

What a beautiful rifle! We do need more pictures to be posted.

My friend Ka'imiloa whose restoration project I posted about over here lives not very far from you and he had similar problems with his Calderwood 500 BPE which he solved very mathodically. In case you need his assistance, I would be most happy to introduce you to him though he is travelling in HAwaii this week and would be back after Easter.

Thanks for posting and good hunting!
