I found out which kilt I have!!

Turns out it was made by Thomas Gordon & Sons Ltd. from Glasgow. THe label it kind of faded, but I think it says:

KILTS NO. 1 BLACK WATCH 0.5
Size:- 6
Height:- 5ft.3"-5Ft.4"
Waist:- 32"
Breech:-39"

THOMAS GORDON & SONS LTD.
GLASGOW

Again, I think that's what it says. Also, it looks like there's a stamp on it that reads either "SERIES54" or "SERI954" or something similar.

I've been looking and one recently sold on a South African bidding site for 1,999.00 Rand, or about $200. Not bad for a first kilt, eh? Especially for a teenager.

EDIT: I measured the yardage, it came to about 7.5 yards.
