Can anyone identify this trigger housing?

I received this trigger housing with a collapsible stock I bought. Seller told me to just keep it. Can anyone Identify it? The only marking on it is a stamped 376.

sef = hk.

Thanks Joe, I kinda figured HK but was wondering specific application?

[jbruney]

One of the HK boys will pop in soon. My recognition of HK parts is limited to internals, barrels, trunnions, and stuff for the most part, but looks like a 93.

Thanks again Joe.

That could be a grip frame for a 93, or also a 91 that was bobbed down. It also looks like the front pin hole tabs were trimmed off as well.

Yep Im betting its been clipped, but not pinned for semi use. Im not sure if the 33/93 platform ever used a metal trigger housing so Im gonna go with G3 type as it has the F/A markings. Have no idea why it was cut on the back though unless now it fits a 33/93

[lnwilcoxson]

Thanks for the info guys I appreciate it!

[lnwilcoxson]

One last question guys? What would be a fair asking price for it?

Looks like the one for the sp89 only in navy config.
