The
Sovereign Grace Advent Testimony is one example. I haven't looked at their stuff in a long time. They have a good many things on SermonAudio now, including their quarterly magazine,
Watching and Waiting. The last time I checked, many if not most of their speakers are ministers in the Free Presbyterian Church of Ulster. I see that they have a Canadian Representative, but I'm not sure what that means unless maybe that means that he is a distributor of some of their literature. If I'm not mistaken, everything they reprint or produce is post-trib.
The Blomberg book is not really Reformed, at least not in the sense that all of the contributors are Reformed. I'm not sure if any of them are really Calvinistic, but I don't have it handy to be able to check, and the views of some of them on subjects besides premil are unknown to me. But I seem to recall that one brother (a Korean?) set forth a covenantal premil view. It also doesn't deliver on the promise of its title--it is not a "case" for HP in the way that Riddlebarger's book is a case for amil. The book originated from a conference.
J. Oliver Buswell was premil and mid-trib, which is closer to pre-wrath than either pre-trib or post-trib. He covers eschatology extensively in his Systematic Theology, which has been OOP for a good while.
James Montgomery Boice was actually premil and pre-trib. (Some say he switched to post-trib later in his ministry, but I've seen no evidence of that. If there is evidence, I'd love to see it.) His views can be seen in some of his commentaries. Daniel and the Minor Prophets come to mind. He also wrote a short work on eschatology,
The Last and Future World, that is long out of print. (One former associate of his, an amillennialist, has said that wishes the book would disappear and that its disappearance would help Boice's reputation. (My words, but I recall that being the gist of what he wrote on a blog somewhere.)) Boice and some other Presbyterians of his era couldn't be considered dispensationalists because they upheld the unity of the covenant of grace, which no Dispensational can do.
Francis Schaeffer is another one, but you really have to go digging into the L'Abri recordings to learn much about his views in any detail. A few years ago,
I transcribed a portion of one message where he explains his view in contrast with amil on the one hand and dispensationalism on the other. I think people just assume that he must have been post-trib because he was a Presbyterian. But that wasn't the case.
Michael P.V. Barrett is Reformed and premil and also pre-trib, or at least he was the last I knew. That will be surprising to some given his sharp criticisms of dispensationalism as seen in his series that can be found on SermonAudio. But even there he says he is premil and pre-trib but insists that doesn't make you a dispensationalist. He has a short book on Daniel, but I'm not sure that he goes into a lot of detail, and I don't know where else he might go into any detail.
Barry Horner's
Future Israel is pretty much a must when researching this, even if you object to it here and there. It could have used better editing, and it is a polemical work. It isn't about premil per se so much as it is a defense of "Zionism." (From what I can ascertain, that was a common if not universal view among "Historic" premils prior to the 20th Century, (and maybe until the mid-20th Century) and it long predates Darby.) But he doesn't quote any Dispensationalists. He quotes a good many Reformed/Calvinistic premils, such as Spurgeon, Ryle, and Horatius Bonar, as well as some postmils such as Edwards and a'Brakel.
As you might expect, Spurgeon's views are scattered throughout several sermons. I can't remember to what extent he addresses it in his commentary on Matthew. See
here for a good essay on Spurgeon's millennial views and
here for his views on Israel. Ryle's book on the subject is
Coming Events and Present Duties, recently republished by Christian Focus as
Are You Ready for the End of Time?. I want to say that he delves into eschatology in some detail in his Luke commentary as well when he gets to the Olivet Discourse. (The Luke commentary is quite a bit longer than the Matthew and Mark commentaries, so I think he spends more time on it in that one.) Horatius Bonar edited the Quarterly Journal of Biblical Prophecy for several years and wrote a book entitled "Prophetical Landmarks." (You can find some of these olde books on Google Books and/or the Internet Archive.) His brother Andrew was also premil, as was Robert Murray M'Cheyne. I think Andrew Bonar wrote at least one book on the subject.
Some of the Independents who took part in the Westminster Assembly were premil. (I don't know whether or not any Presbyterians were. A recent biography of Jeremiah Burroughs notes that it sort of broke down on Independent vs Presbyterian lines.) Burroughs wrote a commentary on Hosea.
The late Robert Duncan Culver was Calvinistic and was an ardent premillennialist. He did not like covenant theology, however, so couldn't be considered "Reformed," especially by the standards of this group. He took no position on the timing of the rapture and believed that it was veiled for "moral" reasons.
I'm an admin for a FB group, Historic (Classic) Premillennialism, which is basically a Calvinistic group.
I think most pre-wrathers consider themselves to be dispensationalists. I know of one who considers himself to be HP. But Rosenthal says he is a dispensationalist, and Alan Kurschner is a Progressive Dispensationalist.
