I'm having the same issue. I equipped these:

And got these (rather ugly things):

@meatshake-0 they look fantastic with the Ambassador hull I’ll tell you that.

Same issue, no idea what these cannons are but they're clearly not the ones pictured on the select screen. Draped in some cloth that's the right colors for Merchants but idk, way bulkier. Looks almost like they'd fit with the new Zeus set added in the plunder pass.

@orifice-spud said in Unexpected cannon cosmetic:

When I equipped my Merchant Alliance cannons today, I was confused at finding what appear to be the Merchant Ambassador cannons sitting on my deck, resplendent in all their blue-drapery white barrel finery. While I appreciate the shiny, I did not think this skin was even available to earn until at least next month. The original Alliance cannons appear in the cosmetic thumbnail, but the Ambassador are what show up to the party. They seem to have replaced the Alliance cosmetic in much the same way as the Reaper cannons replace lower tiers.

The GH and OoS cannon cosmetics seem to be selectable as per usual. No freebies there.

I know, gift horses and all that, but my crew has a near-superstitious attachment to the original Merchant Alliance "purty blue" cannons and insist that they shoot better, or straighter, or something (I know, I know, but if they're happy I'm happy).

I'm just here to like the superstitious attachment comment. :)
