    This 1937 nickel plated Primus No110 has been gathering dust for a while.
    Although in good condition for an 83-year old stove, it still needs to be fettled and is now next on the list to be dealt with.

    I want to add the heater attachment, but getting the original heater attachment would be like looking for a needle in a huge hay stack, so I have the ambition to recreate it myself.

    In this thread 155R - Bowl fire kit for Primus stove
    two heater attachments with different dimensions are mentioned:
    155R - reflector bowl diameter = 27.3 cm (10 3/4 inch)
    157R - reflector bowl diameter = 32.5 cm (12 inch)

    From this https://classiccampstoves.com/threads/primus-110-heater.34036/ thread I learned the 157R type reflector bowl appears the right one for the. No110.
    Apparantly 3 options for the polished bowls were available: brass, aluminum and copper.

    Both 155R and 157R appear to have a domed radiator cap with a diameter of 11 cm.
    A brass domed radiator cap can be from Parafinalia: Primus Radiant Dome
    A picture of arm/support for the domed radiator cap as found in a post in these threads
    Primus 110
    Primus No.110
    will be helpful to create my own.

    The blueprint for the reflector bowl supports is found in Doc Mark’s excellent post:
    Primus 110 Heater Bowl Supports.

    In my case the reflector bowl itself is likely going to be a Tilley/Bialladin bowl or a stainless steel mixing bowl like this one https://classiccampstoves.com/threads/bowl-transplant-for-a-bialaddin-bowlfire.14308/

    To start the hunt for a alternative for the origonal reflector bowl I am looking for 3 dimensions:
    • diameter of the bowl (is 32.5 cm/12” correct?)
    • how deep the bowl is
    • arc length of the bowl (to approximate the radius, given the diameter and depth are known).
    I would be very grateful if somebody who owns this bowl could share these dimensions!
