"Help is need to identify the model of a Blackstone Engine. The engine was manufactured in 1926. It has a serial number of 159888. I'm told it's an AV, & has a mushroom air filter"

John -- this may be a modified duplicate of a message which has disappeared from the screen! So, start again JIC.....
I have a 12.5hp Model B SFC. That's 148655, built 1920, & that has mustroom air filter -- or should have, as that's one of the missing items.
The mushroom air intake was used on many Blackstone models from the mid teens onwards, so that narrows the field but not a lot! Must confess I don't know what a scroll inspirator is......
Give us some clues, & ideally a piccie. What's the HP and/or bore? What size are the flywheels? Most important, what fuel does it burn -- fuel-oil or kero? Does the manufacturers plate say Carters Patent or Spring Injection? Lamp start? Does it have the air pipe running above the cylinder typical of many Blackstones?
Have you contacted MichaelStamford at aol.com? His web site (try Google) gives a potted history on Blackstone models, & he has some original factory records. He also sells repro literature. He's just sent me a manual for Model ACG/ABC/ABP fuel oil engines.
I've checked my literature as follows :-
1906 Instructions for Blackstone Type W oil engines
1912 Blackstone Oil Engine catalogue
1920 Blackstone Oil Engine catalogue
1920 Instructions for working horizontal cold start kero engines
1923 Instructions for fuel oil engines
1925(?) Instructions & Parts List for Spring Injection oil engines
None of those list the AV, 'tho they list a bewildering range of model designations. I'm afraid Blackstone designations require research worthy of a Ph.D. The 1912 catalogue does list AW & AWC as standard oil engines.
Patrick Livingstone in Oz has many pix of local Blackstones. Most make me green with envy. other than the most amazingly painted SFC Portable at a recent Nationals. Purple & puce, or similar ........ Might be work contacting him for local expertise. I'm sure you have more Blackstones out there than we have in Blighty.

"I would like to know what colours the engine would have been painted & what pin striping would have been on the engine."
Leicester Museum have a Model A SFC fixed base engine (the type with the air compressor cylinder attached -- as is mine). It is well painted in authentic colours & lining, in the style used by all Blackstone horizontals of the period. I have a many detail pix of this engine, & could send you a CD.
Mine is in an indelicate rust colour, with almost no trace of the original colouring. Blackstone colours have been matched to current BSI paint numbers. Can supply those references.
Contact me off-list (gwbert at email.com) if you think I might be able to help. If you include a pic or two, that would be good.
