Burning Flames Brown Bomber open suggestion can be found here: https://backpack.tf/suggestion/68c8365032f317277101cb9d

Taking 187.5 keys for this, plus the one odd key gives us 188.5 keys.

Given the recency of these two listings, the 1:1 (+1k) for the Brown Bomber should be fine.

One sale in-date at 188.5 keys, rounding this up to 189 keys, and taking that for the value.
