are these the only parts missing to have a complete UFS?
No
Can one improvise?
Not without the remaining parts listed in the GGTS/AVS/UFS Guide
How hard would it be to
buy it from someone that may have a spare and would be willing to sell?
Currently running 275-300 USD when found for sale
Is the UFS top cap different than the GGTS adjustable draw cap?
Yes, see explanation below
Sorry for the buttload of questions and I know that this same questions were posted before but I wasn't able to find the thread!
thanks in advance, nice GG peeps!!
Not a problem! As time allows, more and more parts will be available for spares but at present, only items thought to possibly need to be replaced with time/use or in the case of the solid steel window or stainless mouthpiece, both upgrades are currently available when stock is available.
At present, there are a little over 300 UFS in circulation so the price for an extra or one not being used reflects this. Imeo has stated in other threads that more are being made and expects the lead time to be approximately mid-November. The US price is $149 before the "bigbuyer" 10% discount.
The new "top cap" for the UFS as listed is not a true top cap in the literal sense of the word. It is a screw in replacement for the original mouthpiece that allows the user to utilize longer attys/cartos as well as use the drip tip of their choice. The top cap which is seen covering the top of the tank itself is a separate piece not currently for sale as the efforts are to build full units.
The top brass cap of the current GGTS serves a similar purpose but is a totally, non-intercgangeable part from the UFS "top cap" listed. I tried to give a brief/short answer in your quoted text in color to highlight the answer. Rest asured Imeo is making items as fast as he can make them to meet the standards of quality in craftsmanship that defines the GG series.
Sub-contracting parts or any manufacturing not under his control might mean larger numbers but would not meet the criteria of being what Imeo demands and GG users have come to expect. Waiting is tough but when you can wait and buy from a retailer, the price is reasonable to go with the unmatched quality of any item bearing the GG logo.
Hope this gets at your basic questions and if not, we have much more experienced hands that will jump in and respond!
