BSA/Lincoln Jeffries Rifles.

If I were to come accross a BSA Imp Mod D Light Pattern with a serial number pre-fixed with the letter S, would this indicate that the trigger block had been switched/substituted with one from a BSA Standard pattern? All the L Pattern rifles I've seen have had L pre-fixed numbers.

Hi Harry,

The letter 'S' in front of the Ser No on the Improved Mod D denotes that the rifle has a double sear fitted. This was a rather unsuccessful safety related feature introduced during the final stages of production.

That is a useful piece of info.

HI, there should also be a stamping of a patent number (or very often) on the block, which covers this mod ..can't remember it at the mo'.... The trigger set up is shown well here;

This set up can be spotted by simply looking closely at the trigger from underneath on a complete gun. The piston rod has two latch cut outs as well.

It was an early anti-beartrap effort, which depended a lot on the balance being correct between the upper and lower trigger / sear spring set, It seems they had problems with it, as many guns seen have the whole shebang riveted to prevent movement, and made basically into a normal trigger.

I have had maybe 10 of these equipped guns apart over the last few years, and the riveted triggers seem to be more common by about a 60% margin in the ones I have seen.

It was as per normal with BSA back then, announced with a lot of hoo-haa, and then quietly dropped because it did not prove as reliable as expected. Unusual for BSA back in this era to get stuff into production like this, I think that apart from this (along with the ''improved'' 1930's post and heavy ring washer retainer which can be a mare), and arguably the weak stock / action joint area, that generally they got it spot on.

When I say weak above, it is only an issue when the stock bolt / trigger guard screws are not kept tight, but they did do a supplimentary third screw on the top of the cylinder, or at least someone did from time to time as these are sometimes seen.

ATB, Ed

Thanks for that, I thought smoeone was trying to pass a bitzer off as the real McCoy. It would seem my scepticism was mis-placed.
