Driskill your photo nailed exactly what I was having a mini rant about-there are so many! Every time I looked in the Blue Book or online I never seemed to see the same model twice! I particularily like the quarter stocked rifle which has that "period" look captured by early BSA and Webley models.
I must compliment you, if those are your collection then your dedication is faultess. I may have a Milbro one or parts of one kicking about, its a strange thing how ones tastes change, just a few years ago I would not have given the 27 a second glance but now I find them a very worthy rifle indeed. In fact with so many different manufacturers I can understand your fascination with them... I cant think of any other design being so widely copied though the Gamo 440 has a fair few imitators!
Thanks for sharing the pic I have duly saved it for future reference and I will before the end of 2023 have at least one Diana 27 in my collection. This thread may well be resurrected after the first purchase
