Model 52 speedlock problem

I have a very nice model 52, serial no. 23258, that fails to stay cocked when the bolt is closed.  It worked fine the previous time I had it to the range. I have tried adjusting the trigger pull screw, both clockwise and counter clockwise, with no effect.  I tried a different bolt (from the same time period serial no. 24344) and it also wont stay cocked.  When I put the bolt in the other 52 #24344, it works fine.  I would guess it must be a problem with the sear.  Any suggestions?   Is there any place that might have a new sear available? 

Thanks for your help,  Roger

Is it the function of that little coil spring in the forward part of the sear body to keep the sear tip up in the right position?

Clarence, I have had very little luck in finding much information on how the system works.  I only have the Houze Model 52 book to go by.  I have no education concerning what does what.  You may be correct in your summation, but I am not sure which spring you are referring to.  I have the feeling that the sear is not making firm enough contact to the catch on the firing pin spring.  I thank you for input.  Roger

That's all I have...and for explaining mechanical details, it's useless. 

If & when 52-expert Seewin notices your question, you'll get a definitive answer.

Thanks again, Clarence.  I have never had reason to seek any kind of repair or had a problem with any of my few 52s until now.  There has been no need to mess with a great action and removing the bolt is the extent of my knowledge.  "If it ain't broke, don't fix it", is my motto.  I appreciate your candor.  We will wait and hope someone has an answer.  Because this particular 52 has a special "deluxe type" stock and special Wittek-Vaver sights I have a feeling there may have been some unnecessary "smoothing" done to the sear.  Just a guess, but I will not be surprised if that is the case.  Roger

Up date!  Model 52 is now working perfectly.  The problem was so simple and I missed it.  Had a guy that builds precision rifles take a look at it and bingo.  He noticed that the trigger was contacting the trigger guard and not returning to a full forward position.  I haven't a clue why this would occur as the guard shows no signs of being bent.  I stoned off a little of the trigger end and everything works as it should.  Thanks all, just wanted to close this out.  Roger
