Yes.
I received the S2+ spacers. Put one together, no problems. 
C8TT head for M21A threads
Alu head for 40mm anna optics
Brass retaining ring for 17/20mm driver
Cu spacer
Stainless bezel
AR coated glass
O-ring
Is it possible to taper the outside diameter of the cooling fins down a little towards the battery tube?
I am probably not the only one who would purchase this set.
If it will be rethreaded for M21A tube, several fins will fall down.
What about a new design to accommodate the larger tube… not a rethread?
C8TT was developed as test stand. I wanted such project for myself but decided to make a batch to make it available for others. This project is not profitable, machining time is long so it was more reasonable to make 20 or 30 simple spacers instead.
There is also another problem. Simon get so many requests about new convoys so I guess there will be changes in dimensions. I wouldnt like have batch of parts that dont fit actual batch of hosts.
Also, have found few rare items:
Left is for SK-68 and right is for HD-2010.
I’ll take sk68 with my next order. Can you keep it for me?
Sure.
Could you produce some more SK68 copper pills?
Yes, if you are ready to pay $10/pc.
I’m not sure if these pills fit a SK68 clone of mine. Could you please tell me the height and the diameter at the top and at the threads?
Top is 21mm, threads are m19x1.
Thank you for the sizes, but I have another pill. I will order some other things then.
I was excited to see a small package from Russia in the mail today! A quad spacer for the Convoy S11 is all the rage these days… 
or should be soon. The host and emitters are still in transit from China though. Thanks kiriba!
Recently I received the items from my first order from kiriba-ru. They arrived in two weeks with full tracking. The packaging is incredibly well done, every single item is in a plastic bag, wrapped with foam, then wrapped again and glued with tape. 
I’d like to share some fotos of the C8TT head with Ledil Anna 7 copper spacer as it is a real beauty and I never expected it to be that nice. 
S11 sets sold.
Last one rejected S2+ triple pill is available.
No plans for big batches anymore, demand is very low, it would take years to sell another batch.
I still have many single pills and triple spacers, if anyone needs triple pill I can solder spacer and single pill together and drill a through hole so they could replace a regular triple pill.
How much for shipping to South Africa?? It will be the deal breaker, if the Paypal fees aren’t already.
I will send a pm soon, thank you.
