hi everyone, well my learning is continuing and would like to ask for some help with buying spare tip adaptors. I ordered a pack containing 3 shrouds loads of tips and 1 tip adaptor and but stupid me ordered a righthand tip adaptor instead of a left but no problem the supplier sent me a freebee lefthand which fitted perfect. my question is apart from the threads how do you tell the difference between left and right if looking at them? in the pic im uploads I have 3 , on the right my original which came with mmm100 and is lefthand thread. the middle one is freebee I got yesterday also lefthand thread and one on right is righthand thread. the one which arrived yesterday the freebee has like a collar on bottom but other 2 havnt. any help id be most gratefull for. many thanks in advance.
