So I got this really cool looking MM corn cob from an antique shop recently. For 7 bucks! It's a straight stemmed churchwarden. I only say it's an MM because it isn't a soft or flimsy cob like the china-made ones. It has a really solid bottom and the typical finish some of MM's cobs have. But anyway, the stem fits into the shank crooked. I've checked the stem and tenon and they are perfectly straight; it's the shank fit that is drilled a tad crooked. So any suggestions on how to fix that? It's a great looking pipe, and I'd hate to try and find another cob to fit it (especially because I think the MM tenons are thicker than this one).
