Hello 450 366

Send an e-mail to Dave Mansom at Dave Manson Precision Reamers. I think you can contact him at david@mansonreamers.com I get all my reamers from him. Very good product at a reasonable price. I know he does the 577 3" because I purchased one from him about 12 months ago for a 577 3" double I'm building. I actually need to get around to putting an up-date on this project on this forum.

Regards
Alex
