Offered for your consideration is this Sievert Svea 123 burner bell. It is nice and round, and the threads are very good. There are two marks on the outside, and a spot of metal on the inside. It is hard to tell, but it looks like there were holes that were filled in with some brazing material. The job was nicely done, whatever the reason/history. Please note, this fits Sievert stoves only, it will not fit an Optimus 123 or 123R.

International shipping; For many countries, tracking is available with International First Class. If your country is not one of these, then I strongly recommend Priority Mail, which does include tracking. I will ship First Class to save you money if you choose, however, you must take the risk of it being lost in the mail. Please e-mail with any questions.

I'll ship same or next day after payment 
Please, no returns, PayPal only, and please pay right away (within 3 days) 

Combined shipping policy; if it fits, it ships together for one low price. 
Wait for invoice if eBay doesn't combine for you. 

I ship via U.S. Post Office mainly; 
Priority Mail flat rate box/envelope or regular box/envelope, with tracking 
First Class Mail, lower cost and a bit slower, with tracking 
FedEx for frames and wheels, with tracking
