Default 1911 mainspring housing help!

Hi everyone.
I'm having a problem with my 1911. I'm trying to remove the mainspring housing, but the housing pin just won't budge. I've tried putting oil around it and even after that it won't move at all. Does anybody have any suggestions on how to remove it? Thanks.

Here are a few photos of it

Make sure the hammer is at rest/down, not cocked. I use an old .45 firing pin as a drift to remove the MSH pin. The nose shape of the old firing pin is a perfect match for the hemispherical end of the MSH pin, so it won't slip off as you're tapping. A couple of firm taps with a light hammer removes the pin on any of my guns. If yours is rusted or tighter for whatever reason, it will likely require heavier/more taps with the hammer to remove. Make sure the frame is well supported and the pin has room to move when you get it started out. I use a synthetic bench block to support the pistol's frame while removing the pin, and an 8 oz. or 16 oz. brass gunsmith's hammer...ymmv

I tried all if that. But while stripping it down, I made the big stupid mistake of leaving the MSH for last, so the hammer, sears, and thumb safety are already out. Do you think that's effecting it being removed?

Nope, MSH should just slide out once the pin is drifted out. I have only had a MSH that was hard to install and remove on a couple of ocassions. Those MSHs were intentionally machined oversized to allow a very close/tight fit. Even with those, the pin comes out normally. I remove the MSH first when detail stripping the frame. If the MSH fits tighter than the average in the frame, cocking the hammer puts pressure on the MSH and assists in it's sliding out. The MSH pin retainer, interlocking with the groove in the MSH pin, should be the only thing holding the MSH pin in the frame. The pin may be tight due to incorrect diminsions as manufactured, interference fit, deformity, rust, etc. But, with the frame properly supported, and enough force applied via hammer and drift, I know of nothing that would prevent the pin coming out of the frame of a 1911 pistol...

Nickel plated colt/savage 1911 chambered in 45ACP. Most of the markings indicate that it was manufactured around the year 1918, but I'm not too sure. I acquired this gun from my great great grandfather, but Unfortunately, the SN had been removed, so the only way I'm certain of this date is by the stamps on the gun. But I am in love with this gun.

It may not have S/ns. I'm sure C3 could enlighten us in that regard.

My grandfather's was built within the second 500 to leave the factory. It has a serial, so is there a reason this one wouldn't? Maybe a special version?
