Dumb question, but hoping someone here might have a lead. Need to replace my belt pouch for my L-508 Sekonic

Hi guys, I have what is now considered a rather old Sekonic L-508 spot/inc meter. My belt pouch is kaput, torn to shreds from excessive use (a good problem?). However, for the life of me I can't find anything online to replace it. It seems the only pouch of similar size that Sekonic offers is this monstrosity. It's a horizontal zipper pouch instead of my vertical velcro pouch. None of the other available once match the dimensions of the L-508 close enough for me to risk buying them.

So, long shot, but has anyone else here dealt with this issue? What do you use to carry your meter with you? Thanks for any tips you can provide!
