WTD: Late 90's Bomber Z1's (or just crown) for Spares

[Northernlight]

Noticed a crack in the crown of my old Z1's at the weekend (circa 1998 with the crown than bolts onto the legs). As they are on my retro LTS i'd like to keep the bike original.

Anyone got a spare set lying around? Don't need to be working as long as the crown is intact and the steerer is a decent length!

Cheers
