N/A Record Jumbo - Oval Mainspring in a Concentric Air Pistol

[vintageairguncollector@gm]

Hey AGN gang,
Just picked up another concentric air pistol for the collection. Very happy I found one of these. It was unfired until yesterday. The fact that it's the only spring air pistol made with an oval shaped compression chamber that I have ever seen. I am fairly new to air pistol collecting so there are lots I've never seen. The oval mainspring and chamber make this a desirable item according to the write-up in the Encyclopedia of Spring Air Pistols.

It is odd, that the screws on the cocking level are marred on both sides of the gun. The only marks on the airgun are factory errors. Does anyone else have experience with these air pistols?

Service Guide for the FB Record Jumbo

In this article, for a change from writing historical pieces, I am going to write a guide that details how to disassemble a Record Jumbo. Why the change Jimmie? Well, I bought this pistol rather cheaply at a bring and buy sale some years ago. Bargain it was or so I thought. When I got it home when I

so, you jumped into the deep end of the pool on that purchase
so first off go to Protek in the UK and put their kit in with the pistol to have, it is at the bottom right side of this page

that seal is being made in the UK by a very cleaver guy and to have one is important
the rub marks would indicate that the arms are bent in and have been for some time and i guess could be bent so they would stop rubbing
parts are near impossible to find

You are right about the deep end the pistol's seals are failing. Lucky I ordered the Protek seals you suggested Thanks

good to hear you should enjoy that pistol it is a rather rare and odd pistol and they are seldom seen for sale

Philip at Protek is a great help. Cannot thank you enough for helping! I love airguns. Are you going to the Central PA airgun show in April?

Looking forward to meeting more airgun collectors/shooters. I collect Hy-score, Accles and Shelvoke and Healthways and Japanese copies of Dianas BSAs.

no i live in Washington state
i see you are in big with Hy-Score, people are asking very absurd prices for those now
i went down the Diana rabbit hole with 5's and 6's and 10's
and a lot more rabbit holes
till about a year ago there was no oval leather seals available
one of the members on the UK forum decided to make a mold and made some for himself and after that it was i will take one and i will take one and then i saw them on Protek and that effort from him is now saving the pistol

I ordered the Seals from Protek thank you very much! I thought I responded to this thread before. I appreciate your help very much. Lots to learn. Ordered the BSA 1905-1939 book too another rabbit hole yet undiscovered HaHa!

Peace out bro.

Interesting engineering.
Maybe a hobby experiment from one of the Honda engineers/designers years ago, that made a Honda race engine with...yes,,,oval pistons.
