help Identifying unknown Ritchey from late 80"s

[Coquitlam Geoff]

Hey Ritchey aficionados, I recently picked up a Ritchey bike but am unsure as to the year/model. Its 86-89 as it has chainstay XT brakes. The serial number is 7T 001 99. It has the braze on tire pump nipple on the upper seat stay.
Any help in identification would be greatly appreciated. I am guessing based on the Ritchey website that it may be an 87 model may be a Timber wolf? Tig welded.
cheers gents from Vancouver

quick update the serial number is: T7K 001 99
thanks

My best guess 87 Timberwolf tig welded frame though
The brake on pump holder is the mystery
I don’t know which models had the seat stay pump braze on
