Underwood Trigger Housing Inquiry

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

   Here is an Underwood trigger housing with a beveled rear
receiver lug and full width mag wall. It has a trigger housing pin, with
spring, that looks like it has been on the housing for a while. 

What serial range of Underwood receivers had forward lug
slots that were manufactured for use with the early housing pins? 1,350 to 1,360??
Any help would be appreciated. Thanks, Skippy

	According to CC NL 127-2, spring loaded trigger house pins are found from 1,350,000 through 1,365,xxx. Is the sear marked?

	Yes, the Sear is marked . U . on the underside. Thank you for the quick response Hunterman. By-the-way, I am going to buy the full CCNL set. I understand it contains a wealth of information and it also helps support this site. It certainly would have answered this question! Thanks again.
