Thanks DP, I just found out that if you already have a Tilemahos, one can just buy the base and AFC ring and tank and you can use the rest of the Tilemahos parts with the 20mm parts above.
I did get Toolmans V1 21mm and I do love it
Whats funny, is he was going to "gift" it to me, ( I hope its ok to post this) and he just left me with a "if you ever see one of these"
I had a spare of that item, and I automatically thought, should I? Took only a few moments to decide.
Ended up a trade and Im truly happy. He got something he'd been wanting for while all for being so generous and kind.
