Source for L1A1 Breeching Washers

[Original_Sled_Dog]

Hey guys,

I'm getting set up to do an Aussie build and I've got everything I need except for the locking shoulder and more importantly, the breeching washer. I can't get a headspace read to figure out the locking shoulder without the barrel timed up so I'm in a pinch. I've tried all the usual suspects (Gunthings and Gun Parts guy) and Pat at SAFLithgow seems to have absconded.

Any suggestions?

Thanks!
