Home » 30 » Selling collection

To make selling my brazing parts collection easier I will create "lots" with a description, as far I know. Parts often have no markings, and designs are copied by other manufacturers. So there will be mistakes, sometimes by me , sometimes by others.


Who wants to buy a lot can send me a mail. Payment through PayPal, I will send a request; when payment is recieved the lot will be sent by mail ($24 upto 2kg of parts, Track & Trace $6 extra) ; the picture on this page will be removed after payment.


Who wants to buy one item should buy the whole lot at the fixed price.   wjemvdb@gmail.com
