Hello, how are you doing ???
It was so nice to meet you last week at SRT.
Regarding this enquiry, we can not make a contact with the end user who is in charge.
(I heard the PIC, Mr. Suriyan takes a off for his wedding.)
To quote for this, we definitely need information of Air Shaft.
Please wait for our quotation until the day when we can make a contact with Mr. Suriyan
Or can you get the Air Shaft information or DWG from TSUBACO ???
