Hi Jim,
nice to hear from you, thanks for the reply and comments

. You have re-inforced my feeling that the sheath is too wide. I should be able to slim it down by approximately 1/2".
As to colour (color

) significance I found this.....
...."The saffron colour is considered auspicious by Hindus. This color has a special significance to the Buddhists, Jains and Sikhs. Among the Sikhs it is considered to be a militant colour signifying a fight against injustice. Saffron coloured triangular flag is considered to be a religious symbol.. This flag is seen flying atop temples (Mandirs) and Gurudwaras."...
This is colour linked to religion, interestingly Green has similar meaning to Muslims. I can find no reference to colours that represented region/ kingdom alliance/Ruler or other belief 'criteria'.
