Identify bike manufacturer using the number 1857 and is made in England

I'm not sure what it is, and I'm not an expert, but I'm pretty sure that's not an Abeni.

Googling around suggests that there are a lot of bikes out there where people have put Abeni stickers on a non-Abeni frame. Apparently, Abeni frames almost always have the word "Abeni" stamped at the top of the seat stays and Abeni forks and head tubes usually have a big ol' A on them. Furthermore, Ezio Abeni was an Italian who emigrated to Australia and started building bikes there: his bikes wouldn't be made in England.

I might have traced back some info on it:

This forum talks of Healing track bikes and one user mentions the underside of his BB is marked G.R. 23 and England, with serial number marked upside down on the seat clamp.

From there I searched for images of Healing track frames and stumbled into this picture, which would match the headtube style. The lugs are different, but hey, this one is from the 1940's...

So my guess is that it's a Healing track bike as it indicates

Importing bicycle parts Healing was quickly gaining a reputation for his quality and service among the cycling community[...]

Which would fit with the BB shell marked as made in England. The decals are definitely just fakery after a repaint.

John Abeni was an Australian frame builder in the 80's/90's.

He built frames for Europa cycles in Sydney as well as under his own name. There were lots of bikes sold with Abeni decals that came in from overseas but a real Abeni was pantographed as described in a previous post.

The lugs and dropouts on this frame look very much like they originate in the 1950's/60's. Even the rear track style dropouts in that shallow style that they have are much older than the Abeni era.

I couldn't say what its origins are but it is a nice frame that I would guess was re-painted by Abeni and sticker-ed up as such.
